MySQL Error 1265: Data Truncated for 'contact_num' Column - Troubleshooting Guide

This warning message indicates that the data being inserted into the 'contact_num' column of the 'practice_anythings' table is too long to be accommodated by the column's data type. This means that some of the data has been truncated (cut off) in order to fit into the column. This can result in loss of data and may affect the accuracy and integrity of the database. To resolve this issue, you may need to increase the size of the 'contact_num' column or adjust the data being inserted to fit within the column's limits.
