I have a string that contains a long SQL structure for retrieving data from SQL Server. Is there a work around solution to have longer string size to contain this long statement ?

Use line continuations to split your statement into multiple lines. i.e.
strSQL = "Use line continuations" _
         & "to split your statement" _
         & "into multiple lines"

Open in new window

About 2 billion characters. I seriously doubt you're even close to that limit.

There is a limit on the number of lines that can be continued

You may have to use string concatenation.
Example:
strSQL = "Select * "
strSQL = strSQL & "From mytable "
strSQL = strSQL & "Where fieldname = 42"

Open in new window


You could also read the SQL string from a file source.

================
Are you trying to store the SQL in an Excel cell?

The SQL statement is coded in a VBA. Any better way to handle this ?

For string size, it is not limited to 255 chars, correct ?

Coding the string in VBA is fine as long as the lines are not too long (use line continuations or string concatenation).
String size isn't limited to 255 chars.
