how to handle dynamic input values in sql server 2008 query.
My scenario is in the below query is im having two input paramanetrs passing from java through i-batis
1) if i enter stlmtTransId field alone query should execute (paymentTransId is empty now).
2) if i enter paymentTransId field alone query should execute(stlmtTransId is empty now).
3) if i enter both input values query should execute for matching the two inputs.
at any of abovr case i need output. how to handle it.
SELECT
STLMT_TRANS.SETTLEMENT_TRANSACTION_ID
,STLMT_TRANS.PC_TRANSACTION_ID
,STLMT_TRANS.TRANSACTION_AMOUNT
,STLMT_TRANS.PAYMENT_AGENT_ID
,STLMT_TRANS.PAYMENT_AGENCY_ID
,STLMT_TRANS.PAYMENT_TRANS_DATE
FROM
T_SETTLEMENT_TRANSACTION STLMT_TRANS WITH (NOLOCK)
WHERE
STLMT_TRANS.SETTLEMENT_TRANSACTION_ID=#stlmtTransId#
AND
STLMT_TRANS.PC_TRANSACTION_ID=#paymentTransId#
Note: im using java + I-Batis
WHERE
(
(STLMT_TRANS.SETTLEMENT_TRANSACTION_ID=#stlmtTransId#) or (#stlmtTransId# is NULL)
)
AND
(
(STLMT_TRANS.PC_TRANSACTION_ID=#paymentTransId#) or (#paymentTransId# is NULL)
)
SELECT
STLMT_TRANS.SETTLEMENT_TRANSACTION_ID
,STLMT_TRANS.PC_TRANSACTION_ID

,STLMT_TRANS.PAYMENT_AGENT_ID

,STLMT_TRANS.PAYMENT_TRANS_DATE
FROM
T_SETTLEMENT_TRANSACTION STLMT_TRANS WITH (NOLOCK)
WHERE STLMT_TRANS.SETTLEMENT_TRANSACTION_ID = ISNULL(#stlmtTransId, STLMT_TRANS.SETTLEMENT_TRANSACTION_ID)
AND STLMT_TRANS.PC_TRANSACTION_ID = ISNULL(#paymentTransId, STLMT_TRANS.PC_TRANSACTION_ID)

New to SSIS, been dealing with SSMS mostly. Anyone can help translating the below SSMS statement into SSIS Derived Column Transformation? Many thanks.
ReliabilityFactorInput = Case
When (isnull(pn.LBOXMATL, 'OTHER') = 'OTHER' AND (round(ISNull(edd.cal_year, eqd.YearManuf) + 1, -4)/10000<=2003) OR pn.LBOXMATL ='Cast Iron') AND (ceiling((pn.NOWAYS+1)/2)*2 >= 4) then '1.3'
When (isnull(pn.LBOXMATL, 'OTHER') = 'OTHER' AND (round(ISNull(edd.cal_year, eqd.YearManuf) + 1, -4)/10000<=2003) OR pn.LBOXMATL = 'Cast Iron') AND (ceiling((pn.NOWAYS+1)/2)*2 < 4) then '1.1'
else ''
End
1.Name a variable with whatever name you want with int data type
2.Use execute sql task
3.copy all the complete query into that task and specify the result Set to single row
4.Switch to Result Set page, choose the variable you create, and set the result name to 0
5.Now every time you run the package the variable will be assigned either 1.3 or 1.1
That variable could be used in Derived Column transformation in data flow now
I have following query against EF whereby mysql was used:
var query = from r in context.myContext
where r.clmn1.CompareTo("2015-11-19 00:00:00") > 0)
orderby r.someColumn
select r;
return query;
The number of returned rows is as expected. however some values of the property r.clmn2 repeat itself in the result of the query. For example I could not find clmn2 == 220011 because it was "overwritten" by the value 220033 (The value 220033 is correct and expected but should not "overwrite" other values). Strangely enough, when I add this condition to the query I get it in the result (of course then only and only this value) which means that the first condition is also valid for clmn2:
var query = from r in context.myContext
where r.clmn1.CompareTo("2015-11-19 00:00:00") > 0) && r.clmn2.Equals("220011")
orderby r.someColumn
select r;
return query;
The same query (the first one) works at DB-level and returns all values (will not be overwritten)
SELECT * FROM myContext.myTable
WHERE r.clmn1 > ("2015-11-19 00:00:00")
ORDER BY r.someColumn
It should be a problem of EF. I hope someone could help me!
Thanks in Advance.
I have prefixed the column/property clmn2 with [key] atribute in the generated entity class so that it is now a part of the multiple key, i.e., with other columns/properties. It works and i get all values from DB. Maybe cus this property comes from a DB-view, Visual Studio could not recognize it as a primary key as done by other properties.
In FoxPro using native table, I usually do this when inserting new Data.
Sele Table
If Seek(lcIndex)
Update Record
Else
Insert New Record
EndIf
If I will use MYSQL as my DataBase, what is the best and fastest way to
do this in FoxPro code using SPT? I will be updating a large number of records.
Up to 80,000 transactions.
Thanks,
Herbert
I would only take what Jerry supplied one step further. When trying to deal with any insert, update, delete with SQL pass through, it can run into terrible debugging problems based on similar principles of SQL-injection.
What if your "myValue" field had a single quote, double quote, double hyphen (indicating comment)? You would be hosed.
Parameterize your statement such as using VFP variable references, then use "?" in your sql statement to qualify which "value" should be used. VFP properly passes. This also helps on data types, such as converting numbers into string when building the "myStatement".
Also, in VFP, you can use TEXT/ENDTEXT to simplify the readability of the commands
lcSomeStringVariable = "My Test Value"
lnANumericValue = 12.34
lnMyIDKey = 389
TEXT to lcSQLCmd NOSHOW PRETEXT 1+2+8
update [YourSchems].[YourTable]
set SomeTextField = ?lcSomeStringVariable,
SomeNumberField = ?lnANumericValue
where
YourPKColumn = ?lnMyIDKey
ENDTEXT
=sqlexec( yourHandle, lcSQLCmd, "localCursor" )
You can use SQL Pass through in your Visual Foxpro application. Take a look at the SQLCONNECT() or SQLSTRINGCONNECT() for connecting to your Database. Also look at SQLEXEC() for executing your SQL statement.
For Example:
myValue = 'Test'
myHandle = SQLCONNECT('sqlDBAddress','MyUserId','MyPassword')
myStatement = "UPDATE [MySchema].[Mytable] SET myField = '" + myValue + "' WHERE myPk = 1"
=SQLEXEC(myHandle, myStatement,"myCursor")
=SQLEXEC(myHandle, "SELECT * FROM [MySchema].[Mytable] WHERE myPk = 1","myCursor")
SELECT myCursor
BROWSE LAST NORMAL
This would be your statement string for SQLEXEC:
INSERT INTO SOMETABLE
SET KEYFIELD = ?M.KEYFIELD,
FIELD1 = ?M.FIELD1
...
FIELDN = ?M.FIELDN
ON DUPLICATE KEY UPDATE
FIELD1 = ?M.FIELD1
...
FIELDN = ?M.FIELDN
Notice that the ON DUPLICATE KEY UPDATE part does not contain the key field, otherwise it would normally be identical to the insert (or not, if you want to do something else when the record already exists)
My database (mysql) tables use TIMESTAMP columns, and whenever I want them returned in a query, I want them to be queried as "UNIX_TIMESTAMP(columnname)".
How do you easily modify queries in zend framework to achieve this?
For example, the current code is:
select = $this->select();
$select->where('user_id = ?',$user_id);
return $this->fetchAll($select);
This eventually becomes:
select * from tablename where user_id = 42;
I want something that automatically finds the TIMESTAMP column and changes the resulting query to:
select user_id,name,unix_timestamp(created) where user_id = 42;
I know I can use a MySQL view to achieve this, but I'd rather avoid that.
Thanks.

You should be able to specify the fields you want in the select using the $select->from() object.
Zend_Db_Select
You should end up with something like this.
$select = $this->select();
$select->from(
array('t' => 'tablename'),
array('user_id', 'name', 'UNIX_TIMESTAMP(created)')
);
$select->where('user_id = ?',$user_id);
return $this->fetchAll($select);
If you wanted to run an expression that doesn't have parenthese in the function, Use the Zend_Db_Expr() method to escape the query properly.
I'm getting this error when trying to run a query that inserts results into a table in sql.
im passing the table name as parameter,how to give the hierarchy value to the insert statement.
here is my code:
declare #pathhere hierarchyid
select #pathhere=Path from SectionDetails where Sectionid=#sectionid and SectionName=#sectionname and Batchid=#batchid and Deptid=#deptid and Schoolid=#schoolid
insert stmt:
set #sqlstmt = 'insert into '+#batch+'(StudentID, StudentName,SectionID,SectionName,BatchID,BatchName, DeptID,DeptName, SchoolID,Path)
values('''+#sectionid+''','''+#sectionname+''','''+#sectionid+''','''+#sectionname+''','''+#batchid+''','''+#batchname+''','''+ #deptid+''','''+#deptname+''', '''+#schoolid+''','+ CAST(#pathhere as hierarchyid)+')'
exec(#sqlstmt)
im getting error in this line:
'+ CAST(#pathhere as hierarchyid)+'
as Invalid operator for data type. Operator equals add, type equals hierarchyid.
can anyone pls help me out how to pass the hierarchy value
You're trying to create a string that can be executed as a statement. So you need to get your hierarchyid into nvarchar(max) instead.
try: #pathhere.ToString()
