Implicit string truncation
Reports variables that exceed the defined length in characters.
Example (Microsoft SQL Server):
CREATE PROCEDURE test() AS
BEGIN
DECLARE myVarOk VARCHAR(5) = 'abcde';
DECLARE myVarExceeded VARCHAR(5) = 'abcde12345';
SET myVarOk = 'xyz';
SET myVarExceeded = '123456789';
END;
The myVarExceeded variable is defined as VARCHAR(5) but both assigned values ('abcde12345' and '123456789') exceed this limitation. You can truncate assigned values or increase the defined length. To increase the length, use the Increase type length quick-fix.
After the quick-fix is applied:
CREATE PROCEDURE test() AS
BEGIN
DECLARE myVarOk VARCHAR(5) = 'abcde';
DECLARE myVarExceeded VARCHAR(10) = 'abcde12345';
SET myVarOk = 'xyz';
SET myVarExceeded = '123456789';
END;
