if {condition1} = '0'

if {condition2} = 'Yes'

Set #SQLQuery = #SQLQuery + ' AND '

As #Pranav states in the comments, you can do the following:
if {condition1} = '0'
Set #SQLQuery = #SQLQuery + ' AND ' +
CASE WHEN {condition2} = 'Yes' THEN <whatever cond2=Yes>
ELSE <whatever cond2<>Yes> END
hope this helps, just assign any or empty value to #SQLQuery before running this
SELECT #SQLQuery+ = CASE WHEN CONDITION1='0' AND CONDITION2='Yes' THEN
' AND '
WHEN CONDITION1='0' THEN
' AND '
END

I want to update my dynamic table in while loop.
Here is my code:
While (#j<=#tmp_getRowCount)
Begin
Set #firstcolumn = (Select SplitFirst_tblAR from #result_AR Where rownumber = #j) //String//
Set #secondcolumn = (Select EMail_tblAR from #result_AR Where rownumber = #j) //String//
Set #thirdcolumn = (Select SplitFirst_tblKul from #result_AR Where rownumber = #j) //String//
Set #fourthcolumn = (Select EMail_tblKul from #result_AR Where rownumber = #j) //String//
insert into #test Values(#tmp_ID, #firstcolumn,#secondcolumn,#thirdcolumn,#fourthcolumn)
if ((#firstcolumn = #thirdcolumn) AND (#secondcolumn != #fourthcolumn) AND (#firstcolumn != ''))
begin
Set #q_updateTable = 'Update '+ quotename(#tablename) +' Set '+#columnname+' = ''' + #fourthcolumn + ''' Where ID = ' + #tmp_ID + ''
Exec sp_executesql #q_updateTable
end
SET #j = #j+1
End
My result_AR table:
I know the error is in here:
Where ID = ' + #tmp_ID + ''
When I change this Where clause as,
Where '+#columnname+' = ''' + #secondcolumn + ''' '
code works correctly.
Why can't I set as ID my where clause? I am getting ID value as integer.
The error is 'Query completed with errors'.
Thanks in advance.
you can not set Id in where clause because the id is integer value and you are concatenating it with string (varchar).
So first you have to convert it in (String)varchar and the you can use it where clause.
Like :
Set #q_updateTable = 'Update '+ quotename(#tablename) +' Set '+#columnname+' = ''' + #fourthcolumn + ''' Where ID = ' + convert(varchar,#tmp_ID) + ''
Exec sp_executesql #q_updateTable
you have to use "convert(varchar,#tmp_ID)" insted of "#tmp_ID"
I want to attach numeric value in dynamic query but I am an getting error:
Conversion failed when converting the varchar value ' + #psRegionCode + ' to data type smallint
My query is:
SET #psRegionCode = UPPER(LTRIM(RTRIM(#psRegionCode)))
IF (#psRegionCode <> 0)
BEGIN
SET #sSQLStr = #sSQLStr + ' ' + 'AND reg.region_cd = ''' + #psRegionCode + ''''
END
Things which I tried:
SET #psRegionCode = UPPER(LTRIM(RTRIM(#psRegionCode)))
IF (#psRegionCode <> 0)
BEGIN
SET #sSQLStr = #sSQLStr + ' ' +
'AND reg.region_cd = ' + cast(#psRegionCode as nvarchar(10) ''
END
Can somone please help me with this?
IF (#psRegionCode <> 0)
BEGIN
SET #sSQLStr = #sSQLStr +
' AND reg.region_cd = ' + cast(#psRegionCode as nvarchar(10))
you need to make sure you have correct number of apostrophes
if #psRegionCode is number, why you ltrim it? if it is a string why you cast it?
Well, by your syntax I'm guessing SQL-Server? Any way I think your second query should work, you are just missing a parenthesis :
IF (#psRegionCode <> 0)
BEGIN
SET #sSQLStr = #sSQLStr +
' AND reg.region_cd = ' + cast(#psRegionCode as nvarchar(10))
END
You can't concat a number into a string without the conversion.
How to rectify error in sp while concatenating the MSSQL queries?
SET #Ws_Sql = 'SELECT CONVERT(VARCHAR(25),#WS_STATUS) AS [Status],A.RECNUB AS [Rec #], A.REVCOD AS [Revenue CODE], '
IF #LNKOPT = 1
BEGIN
SET #Ws_Sql = #WS_SQL +''' AS [Status],'
END
ELSE IF #LNKOPT = 2
BEGIN
SET #Ws_Sql = #WS_SQL +'' + 'Modified' + ' AS [Status],'
END
ELSE IF #LNKOPT = 3
BEGIN
SET #Ws_Sql = #WS_SQL +'' + 'Deleted' + ' AS [Status],'
END
ELSE IF #LNKOPT = 4
BEGIN
SET #Ws_Sql = #WS_SQL +'' + 'Reprint' + ' AS [Status],'
END
Are you attempting to assign an empty value to the [Status] output column, in case #LNKOPT = 1?
In that case, you need to use double apostrophes, to escape the apostrophe character:
IF #LNKOPT = 1
BEGIN
SET #Ws_Sql = #WS_SQL +''''' AS [Status],'
END
which will result in #Ws_Sql containing: '' AS [Status] (otherwise it would result in ' AS [Status] which will give an error when the #Ws_Sql string is executed).

if you want to use single quote inside a prepared statement, escape it with another single quote, example,
SET #statement = 'world''s view';
SET #statement2 = 'world''s view';
from your example above
SET #statement = '
IF(#type = ''F'') or (#type = ''C'') or
(#type = ''D'') or (#type=''F'') or
(#type=''K'')'
-- the strings are all red.
Single quote is used to represent a string literal in SQL.
If you need to explicitly insert a single quote , you should use double single quotes ('')
It should be like this:
SET #statement = 'IF(#type = ''F'') or (#type = ''C'') or (#type = ''D'') or (#type=''F'') or (#type=''K'')'

I am trying to write an SQL query within Visual Studio TableAdapter Query Wizard
My SQL query is:
DECLARE #SQL varchar(255);
SET #SQL = ' SELECT * FROM dbAddress WHERE 1 = 1'
IF #ApexLine1 = ''
BEGIN
SET #SQL = #SQL + ' AND addLine1 IS NULL '
END
ELSE
BEGIN
SET #SQL = #SQL + ' AND addLine1 = ''' + #ApexLine1 + ''''
END
IF #ApexLine2 = ''
BEGIN
SET #SQL = #SQL + ' AND addLine2 IS NULL '
END
ELSE
BEGIN
SET #SQL = #SQL + ' AND addLine2 = ''' + #ApexLine2 + ''''
END
IF #ApexLine3 = ''
BEGIN
SET #SQL = #SQL + ' AND addLine3 IS NULL '
END
ELSE
BEGIN
SET #SQL = #SQL + ' AND addLine3 = ''' + #ApexLine3 + ''''
END
IF #ApexZip = ''

I get the error:
'The Declare SQL contruct or statement is not supported'
If I remove the Declare statement I get error:
'The Set SQL construct or statement is not supported'
Is there a work around for this?
Thanks.
Anything like this:
SET #SQL = #SQL + ' AND addLine1 = ''' + #ApexLine1 + ''''
is EVIL. Don't do it. Variables like #ApexLine1 could contain anything, even something like this:
';DROP TABLE dbAddress--
Think very carefully about what would happen if someone entered something like that in your Address Line 1 field. The only correct solution here is to use the built-in sp_executesql stored procedure. Learn it, use it.
Aside from that, I think at least part of your problem might be that your #SQL variable is only 255 characters. It's easily possible your query is running out of space.
