Why Am I Getting MySQL Error 1292: Truncated Incorrect DOUBLE Value?

MySQL Error 1292: Truncated Incorrect Double Value

The "Truncated incorrect DOUBLE value" error message in MySQL indicates a data type mismatch during a comparison or assignment operation. This often occurs when attempting to compare a number with a string or when attempting to assign a value that is too large or too small for the target data type.

In the provided query, the error is likely caused by a comparison between a number and a string in the ON clause:

ON ac.company_code = ta.company_code

To resolve this issue, ensure that ac.company_code and ta.company_code have similar data types, such as both being integers or both being strings. Alternatively, explicitly cast one of the values to the desired data type using the CAST() function.

Furthermore, verify that the values being assigned to the contact_number column are within the allowed character limit of 15 characters. The error message may also be caused by an attempt to insert a value that is too long for the specified column.

As mentioned in the provided solution, disabling strict mode can temporarily convert the error into a warning. However, it is recommended to address the underlying data type mismatch or value overflow issue rather than relying on this workaround.
