The length of the data must not exceed the maximum limit allowed for the particular column. To avoid this error and insert the string with truncation, use the ANSI_WARNINGS option. When ANSI_WARNINGS is set to OFF, the error message will not be displayed and the data will be automatically truncated to the length of the target column and inserted. This is a useful way to prevent SQL Server from generating any kind of error or warning when inserting data that is too long for the column.
Sometimes you receive the data truncation error in SQL Server, such as “String or binary data would be truncated” and you don't specify the exact source of the error in terms of database name, table name, column name, and truncated values. If you don't care about truncation, you can use SET ANSI_WARNINGS OFF to ignore that type of truncation. If the step size h between two adjacent values is reduced, the truncation error of the difference approximation decreases. A serial truncation error is the error that occurs when a Taylor (Maclaurin) polynomial of nth degree is used to estimate a function.
Truncation error analysis provides a widely applicable framework for analyzing the accuracy of finite difference schemes. When dealing with a stored procedure that inserts 650 fields into a table, it can be difficult to identify which field is causing the truncation error. To make sure that this doesn't happen, it's important to run a select statement to identify which column and row is being truncated. Additionally, TRUNCATE TABLE removes all rows from a table, but the structure of the table and its columns, constraints, indexes, etc.
