Im trying to do a date filter for my report generate form. I have a DateTimePicker with checkbox in this form, If checkbox checked the query will add a WHERE clause.
Currently Im doing this way:-
If DateTimePicker1.Checked Then
query = "SELECT payment_type, sales_payment_dtl.payment_amt, payment_remark, sales_payment_dtl.created_date, sales.inv_no
FROM sales_payment_dtl
INNER JOIN sales_payment
ON sales_payment_dtl.payment_id = sales_payment.payment_id
INNER JOIN sales
ON sales_payment.sales_id = sales.sales_id
WHERE sales_payment_dtl.created_date = '"& DateTimePicker.Text &"'"
Else
query = "SELECT payment_type, sales_payment_dtl.payment_amt, payment_remark, sales_payment_dtl.created_date, sales.inv_no
FROM sales_payment_dtl
INNER JOIN sales_payment
ON sales_payment_dtl.payment_id = sales_payment.payment_id
INNER JOIN sales
ON sales_payment.sales_id = sales.sales_id"
End If
Is it possible to make the code shorter? Because I need to add somemore filter in future, then the code will become very long, Maybe something like this?
query = "SELECT payment_type, sales_payment_dtl.payment_amt, payment_remark, sales_payment_dtl.created_date, sales.inv_no
FROM sales_payment_dtl
INNER JOIN sales_payment
ON sales_payment_dtl.payment_id = sales_payment.payment_id
INNER JOIN sales
ON sales_payment.sales_id = sales.sales_id
IF '"& DateTimePicker.Checked = True &"' THEN
WHERE sales_payment_dtl.created_date = '"& DateTimePicker.Text &"'
ELSE
do nothing"
Simple logic.
query = "SELECT payment_type, sales_payment_dtl.payment_amt, payment_remark, sales_payment_dtl.created_date, sales.inv_no " & _
"FROM(sales_payment_dtl) " & _
"INNER JOIN sales_payment " & _
"ON sales_payment_dtl.payment_id = sales_payment.payment_id " & _
"INNER JOIN sales " & _
"ON sales_payment.sales_id = sales.sales_id"
If DateTimePicker1.Checked Then
query &= " WHERE sales_payment_dtl.created_date = '" & DateTimePicker.Text & "'"
End If

I Tried to run the below Query but its showing an error incorrect syntax near 'unionselect' Can anyone help?

Looking at the error message I suspect you are concatinating a string to make the query. unionselect should be two words, seperated by a space. (union select) I think that in your code spaces are missing to separate keywords.
See:
"...where PERIL=1" & _ "union" & _ "select distinct..."
will produce
...where PERIL=1unionselect distinct...
output. Correct code (notice the spaces around the union):
"...where PERIL=1" & _ " union " & _ "select distinct ..."
So i need to make a strsql like this one :
strSQL = "SELECT "
strSQL = strSQL & " tblclips.fldclipid, "
strSQL = strSQL & " tblPlatenfirma.fldplatenfirmaID, "
strSQL = strSQL & " tblClips.fldUitvoerder, "
strSQL = strSQL & " tblClips.fldTitel, "
strSQL = strSQL & " tblPlatenfirma.fldnaam"
strSQL = strSQL & " FROM "
strSQL = strSQL & " tblClips "
strSQL = strSQL & " INNER JOIN tblPlatenfirma "
strSQL = strSQL & " ON tblClips.fldplatenfirmaid = tblPlatenfirma.fldplatenfirmaID"
strWHERE = ""
But i got a SQL code that I don't understand so with the result I can't make a strSQL, I really need this for a school project and i got a few days left. This is the SQL i don't understand:
SELECT tbluurroosterleerkracht.flduurroosterleerkrachtID AS uurroosterID, tblklas.fldnaam AS Klas, tbllokaal.fldnummer AS Hoofdlokaal, tblvak.fldvak AS Vak, tbllokaal_1.fldnaam AS LesLokaal, tbllokaal_2.fldbeschikbaar AS beschikbaar, tblleerkracht.fldnaam AS NaamLeerkrachtNormaal, tblleerkracht.fldvoornaam AS VoornaamLeerkrachtnormaal, tbldag.flddag AS Dag, tbllesuur.fldvan AS Van, tbllesuur.fldtot AS Tot

It is an unusual SQL query. Are you sure it produces the result you want?
When trying to understand code it is useful to format it so that you can clearly see each part of it. This is particularly true for big SQL queries, and code with lots of nested bracketted bits.
Here is the SQL with my rough formatting applied...

Is there a specific part that you do not understand?
I think despite not understanding how the SQL works. Your string building method should still work as a way to store the sql in a program variable.
I am joining product and cart table to calculate for the total price for each cart. Here is my sql statement:
String sql = "SELECT p.productID, p.productName, p.productPrice, c.quantity, p.productPrice * c.quantity as new_unit_price, SUM(p.productPrice * c.quantity) AS totalPrice"
+ " FROM sm_product p INNER JOIN sm_cart c "
+ "ON p.productID = c.productID"
+ " WHERE c.custName = '" + custName + "'";
I derived a column named new_unit_price by multiplying the quantity from cart table and product price from product table. Then I want to use the derived column which is new_unit_price to sum up the price of all item in the cart. I get the data from the column in database by:
double subItemTotal = rs.getDouble("new_unit_price");
double totalPrice = rs.getDouble("totalPrice");
My new_unit_price works. But unfortunately, my sum does not works. It's still 0. Does anybody know how can I sum up the value from derived column? Thanks in advance.
To use the SUM() function, you'll need to do a GROUP BY at the end of your statement.
This should get your overall cart total:
String sql = "SELECT c.custname "
+ ", SUM(p.productPrice * c.quantity) AS totalPrice"
+ " FROM sm_product p INNER JOIN sm_cart c "
+ "ON p.productID = c.productID"
+ " AND c.custName = '" + custName + "'"
+ " GROUP BY c.custname;"
Also, I changed the WHERE to an AND so it is evaluated earlier and should make the query faster.
If you want the new_unit_price and the cart total in the same query, you have to go back into the tables again to get that data. Something like this should work:
String sql = "SELECT p.productID, p.productName, p.productPrice, c.quantity "
+ ", p.productPrice * c.quantity as new_unit_price, total.totalPrice FROM "
+ "( "
+ "SELECT c.custname "
+ ", SUM(p.productPrice * c.quantity) AS totalPrice"
+ " FROM sm_product p INNER JOIN sm_cart c "
+ "ON p.productID = c.productID"
+ " AND c.custName = '" + custName + "'"
+ " GROUP BY c.custname"
+ ") AS total "
+ "INNER JOIN sm_cart c "
+ "ON total.custname=c.custname "
+ "INNER JOIN sm_product p "
+ "ON p.productID = c.productID "
I have a complex union query that I would like to translate from MS SQL to MySQL using either Laravel's Fluent query builder or Eloquent (just guessing only Fluent could handle it). The other alternative would be to simply us a DB Raw query, but that doesn't seem very Laravelish.
I do this as part of a recurring events engine to connect a past events history table with the futures table that holds the recurrence pattern. Here's the query if you're interested.
qry = "SELECT clients.p_client_id,contacts.last_name, contacts.first_name, "
