i want to add value(string) in my select query..iam using dbquery..do anyone know how to do this?
$tableA = (new \yii\db\Query())
->select("sm_wp.no_agenda,mfwp.nama_wp,sm_wp.jenis_surat,
sm_wp.nomor_surat, sm_wp.tgl_surat,sm_wp.perihal")
->from('sm_wp')
->leftjoin('mfwp', 'sm_wp.id_mfwp = mfwp.id')
;
from that query i got this table in my gridview
no_agenda nama_wp jenis_surat nomor_surat tgl_surat perihal
--------- ------ ----------- ----------- --------- -------
1 xx 1 22 21/10/2019 bla
i want that table become like this
no_agenda kategori nama_wp jenis_surat nomor_surat tgl_surat perihal
--------- ------ ----------- ----------- --------- ------- -------
1 foo xx 1 22 21/10/2019 bla
2 foo yy 1 22 21/10/2019 ble
i want to add kategori in my gridview with same value (foo)..thx
You need to escape the quoting by using \yii\db\Expression
$tableA = (new \yii\db\Query())
->select(
[
new Expression(
'sm_wp.no_agenda,mfwp.nama_wp,sm_wp.jenis_surat,
sm_wp.nomor_surat, sm_wp.tgl_surat,sm_wp.perihal,
"foo" as kategori'
),
]
)
->from('sm_wp')
->leftjoin('mfwp', 'sm_wp.id_mfwp = mfwp.id')

I would like to get max date from other query insert to current query. Look at my codes pls.
Data:
inv_id inv_date inv_export inv_code
1 2016-03-14 0 a2
2 2016-03-13 0 a1
3 2016-04-13 1 a1
4 2016-03-14 0 a1
Result:
for inv_export = 0 return a2 & a1
for inv_export = 1 return a1
mysql (working fine):
SELECT ..., i.inv_date, i.inv_export
FROM Sp.inventory AS i
...
WHERE i.inv_date IN (
SELECT max(i.inv_date) from Sp.inventory WHERE i.inv_export = 1
);
I have tried convert it to symfony:
$qb = $this
->createQueryBuilder('i')
->select('..., i.invDate')
...
->where('i.invExport = :export AND i.invDate = MAX(i.invDate)')
->setParameter('export', $export);
You can use a subquery as follow:
$sub = $this->createQueryBuilder('i2');
$sub->select("max(i2.inv_date)");
$sub->where("i.invExport= i2.invExport");
$qb = $this
->createQueryBuilder('i')
->select('..., i.invDate')
...
->where('i.invDate = ( '.$sub->getDQL().' )');
->andWhere('i.invExport = :export')
->setParameter('export', $export);
hope this help
What I want to achieve is to move the data between 2 rows within one table.
Column A
--------
FN2
1 200x310mm
2 400x260mm[+0.84]
3 500x500mm[+11.34]
Column B
--------
0.0000
0.0000
0.0000
0.0000
This is how it should look like after the data move:
Column A
--------
FN2
1 200x310mm
2 400x260mm
3 500x500mm
Column B
--------
0.0000
0.0000
+0.84
+11.34
What I want is that the query between the [ ] is moved to column B and replaces the 0.0000
How can I achieve this?
Kind Regards
just to illustrate what Yadav said
$query = "SELECT columnID, columnA FROM table";
$result = mysql_query($query,$conn);
while ($row = mysql_fetch_array($result)){
$id = $row['columnID'];
$a = $row['columnA'];
$pos1 = strpos($a,"[")+1;
$pos2 = strpos($a,"]");
$b = substr($a,$pos1,$pos2-$pos1);
$query = "UPDATE table SET columnB = $b WHERE columnID = $id";
mysql_query($query,$conn);
}//end while
edit: Yadav obviously proposed a better answer while I was typing mine...
try this it works for you here i used id as unique key ... and test is my database
<?php
$con=mysql_connect("localhost","root","");
$db=mysql_select_db("test");
$query=mysql_query("SELECT * FROM test where columnA LIKE '%[%]'");
while($row=mysql_fetch_assoc($query))
{
if(preg_match_all('/\[(.*?)\]/',$row['columnA'],$match))
{
mysql_query("UPDATE test SET columnB='".$match[1][0]."' WHERE id=".$row['id']."");
}
}
?>
I found some options to run a mysql query to migrate/split one table into 2 new tables, but one of the fields I would like to create on the new table has to be the same as in the other new table:
So from the "From_payments" table, I would like to create 2 new tables called: "To_paymenttransaction" and "To_paymentinfo". A lof of the field are predefined and some are from the old table. The only problem is that the predefined field "paymentinfoid" has to be the same is both new tables.
**To_paymenttransaction** --- < --- **From_payments**
paymenttransactionid ------- < --- (Generate next available number in this column)
paymentinfoid -------------- < --- (Generate next available number in this column)
transactionid --------------- < --- txn_id
state ---------------------- < --- (Set all to "1")
amount -------------------- < --- mc_gross
currency ------------------- < --- mc_currency
dateline -------------------- < --- payment_date
paymentapiid --------------- < --- (Set all to "1")
request -------------------- < --- (Set all to "NULL")
reversed ------------------- < --- (Set all to "0")
**To_paymentinfo** -----------<
paymentinfoid -------------- < --- (Same generated number that goes to the paymentinfoif field in To_paymenttransaction table )
hash ----------------------- < --- (Set all to "Imported")
subscriptionid --------------- < --- (Set all to "1")
subscriptionsubid ------------ < --- ("2" IF above field mc_gross is 4, "1" IF above field mc_gross is 6, "0" IF above field mc_gross is 10)
userid ---------------------- < --- userid
completed ------------------ < --- (Set all to "0")
Any ideas?
All help is greatly appreciated.
Maybe generate the paymentinfoid on the original table before you split it. Then you can copy that single entry into each of the new tables.
I have this query:-
select col_str,
getVal,another_str,resultVal_str from tablename
Getting results like this:
col_str getVal another_str
'11,12,33,54,1,44' '12' '9,5,4,8,7'
'11,12,33,54,1,44,10,12,11,12,12' '44' '9,5,4,8,7,6,3,5,2,4,2'
'11,12,33,54,1,44' '999' '9,5,4,8,7,4'
'11,12,33' '0' '9,5,4'
----- ---- -----
----- ---- -----
----- ---- -----
The columns col_str,getVal,another_str came from table and the column resultVal_str want to calculate based on remaining three column,
Logic for resultVal_str -
See first record getVal having value 12 and col_str having 12 at location number 2 then see the location number two in another_str is 5, so the resultVal_str is 5 and so on. See below:
col_str getVal another_str resultVal_str
'11,12,33,54,1,44' '12' '9,5,4,8,7' 5
'11,12,33,54,1,44,10,12,11,12,12' '44' '9,5,4,8,7,6,3,5,2,4,2' 6
'11,12,33,54,1,44' '999' '9,5,4,8,7,4' 0
'11,12,33' '0' '9,5,4' 0
----- ---- ----- ---
----- ---- ----- ---
----- ---- ----- ---
How can i add the next column resultVal_str with getting result like above ?
first you need to fin the position of getVal in col_str using FIND_IN_SET function.
once you get the position you can find the resultVal from same location in another_str using SUBSTRING_INDEX function as:
SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(another_str,
",", (FIND_IN_SET(getVal, col_str))),
",", - 1) AS resultVal_str
FROM tablename;
test:
SET #getVal = '12', #col_str = '11,12,33,54,1,44', #another_str = '9,5,4,8,7';
SELECT SUBSTRING_INDEX(SUBSTRING_INDEX(#another_str, ",", (FIND_IN_SET(#getVal, #col_str))), ",", - 1) AS resultVal_str;
I see that within MySQL there are Cast() and Convert() functions to create integers from values, but is there any way to check to see if a value is an integer? Something like is_int() in PHP is what I am looking for.
I'll assume you want to check a string value. One nice way is the REGEXP operator, matching the string to a regular expression. Simply do
select field from table where field REGEXP '^-?[0-9]+$';
this is reasonably fast. If your field is numeric, just test for
ceil(field) = field
instead.
Match it against a regular expression.

Re: IsNumeric() clause in MySQL??
Posted by: kevinclark ()
Date: August 08, 2005 01:01PM
I agree. Here is a function I created for MySQL 5:
CREATE FUNCTION IsNumeric (sIn varchar(1024)) RETURNS tinyint
RETURN sIn REGEXP '^(-|\\+){0,1}([0-9]+\\.[0-9]*|[0-9]*\\.[0-9]+|[0-9]+)$';
This allows for an optional plus/minus sign at the beginning, one optional decimal point, and the rest numeric digits.
Suppose we have column with alphanumeric field having entries like
a41q
1458
xwe8
1475
asde
9582
.
.
.
.
.
qe84
and you want highest numeric value from this db column (in this case it is 9582) then this query will help you
SELECT Max(column_name) from table_name where column_name REGEXP '^[0-9]+$'
Here is the simple solution for it
assuming the data type is varchar
select * from calender where year > 0
It will return true if the year is numeric else false
This also works:
CAST( coulmn_value AS UNSIGNED ) // will return 0 if not numeric string.
for example
SELECT CAST('a123' AS UNSIGNED) // returns 0
SELECT CAST('123' AS UNSIGNED) // returns 123 i.e. > 0
To check if a value is Int in Mysql, we can use the following query.
This query will give the rows with Int values
SELECT col1 FROM table WHERE concat('',col * 1) = col;
The best i could think of a variable is a int Is a combination with MySQL's functions CAST() and LENGTH().
This method will work on strings, integers, doubles/floats datatypes.
SELECT (LENGTH(CAST(<data> AS UNSIGNED))) = (LENGTH(<data>)) AS is_int
see demo http://sqlfiddle.com/#!9/ff40cd/44
it will fail if the column has a single character value. if column has
a value 'A' then Cast('A' as UNSIGNED) will evaluate to 0 and
LENGTH(0) will be 1. so LENGTH(Cast('A' as UNSIGNED))=LENGTH(0) will
evaluate to 1=1 => 1
True Waqas Malik totally fogotten to test that case. the patch is.
SELECT <data>, (LENGTH(CAST(<data> AS UNSIGNED))) = CASE WHEN CAST(<data> AS UNSIGNED) = 0 THEN CAST(<data> AS UNSIGNED) ELSE (LENGTH(<data>)) END AS is_int;

What about:
WHERE table.field = "0" or CAST(table.field as SIGNED) != 0
to test for numeric and the corrolary:
WHERE table.field != "0" and CAST(table.field as SIGNED) = 0
I have tried using the regular expressions listed above, but they do not work for the following:
SELECT '12 INCHES' REGEXP '^(-|\\+){0,1}([0-9]+\\.[0-9]*|[0-9]*\\.[0-9]+|[0-9]+)$' FROM ...
The above will return 1 (TRUE), meaning the test of the string '12 INCHES' against the regular expression above, returns TRUE. It looks like a number based on the regular expression used above. In this case, because the 12 is at the beginning of the string, the regular expression interprets it as a number.
The following will return the right value (i.e. 0) because the string starts with characters instead of digits
SELECT 'TOP 10' REGEXP '^(-|\\+){0,1}([0-9]+\\.[0-9]*|[0-9]*\\.[0-9]+|[0-9]+)$' FROM ...
The above will return 0 (FALSE) because the beginning of the string is text and not numeric.
However, if you are dealing with strings that have a mix of numbers and letters that begin with a number, you will not get the results you want. REGEXP will interpret the string as a valid number when in fact it is not.
This works well for VARCHAR where it begins with a number or not..
WHERE concat('',fieldname * 1) != fieldname
may have restrictions when you get to the larger NNNNE+- numbers
for me the only thing that works is:
CREATE FUNCTION IsNumeric (SIN VARCHAR(1024)) RETURNS TINYINT
RETURN SIN REGEXP '^(-|\\+){0,1}([0-9]+\\.[0-9]*|[0-9]*\\.[0-9]+|[0-9]+)$';
from kevinclark all other return useless stuff for me in case of 234jk456 or 12 inches
