How to Solve Error Code 1175 in MySQL

Error code 1175 in MySQL is typically encountered when you try to create or modify a table without specifying the proper data type for a column or when you attempt to insert or update a value that doesn’t match the column’s data type. This error can occur for various reasons, such as trying to store a string value in a numeric column or attempting to insert a value larger than the defined column length.

To resolve this error, you need to identify the column causing the issue and ensure that the data you’re trying to insert or update is compatible with the column’s data type and length.

Here are the steps to solve error code 1175 in MySQL:

  1. Identify the column causing the issue

First, you need to determine which column is causing the error. The error message usually provides some information about the column name and the data type mismatch. For example:

Error Code: 1175. You are trying to load column 'column_name' from a value that is not a [data_type].
  1. Check the column’s data type and length

Once you’ve identified the problematic column, you can check its data type and length by examining the table structure. You can use the DESCRIBE or SHOW COLUMNS statement to view the table structure:

DESCRIBE table_name;

or

SHOW COLUMNS FROM table_name;

This will display information about each column, including the data type and length.

  1. Modify the data or column definition

After identifying the column and its data type, you have two options:

Option 1: Modify the data to match the column’s data type and length.

If the data you’re trying to insert or update doesn’t match the column’s data type or exceeds the defined length, you need to modify the data accordingly. For example, if you’re trying to insert a string value into a numeric column, you need to convert the string to a numeric value before inserting it.

-- Converting a string to a numeric value
INSERT INTO table_name (column_name) VALUES (CAST('12345' AS SIGNED));

Option 2: Modify the column’s data type or length.

If modifying the data is not feasible or desired, you can alter the column’s data type or length to accommodate the data you want to store. However, this option should be used with caution, as it may impact existing data in the column.

-- Changing the column's data type
ALTER TABLE table_name MODIFY COLUMN column_name NEW_DATA_TYPE;

-- Changing the column's length
ALTER TABLE table_name MODIFY COLUMN column_name NEW_DATA_TYPE(NEW_LENGTH);

Here’s an example of modifying the column’s data type and length:

-- Changing the data type from INT to VARCHAR and increasing the length to 255
ALTER TABLE table_name MODIFY COLUMN column_name VARCHAR(255);
  1. Verify the changes

After modifying the data or the column definition, you can attempt to insert or update the data again. If the error persists, double-check your changes and ensure that the data matches the column’s data type and length.

By following these steps, you should be able to resolve the error code 1175 in MySQL and successfully insert or update data in your tables.

Remember, it’s essential to have a clear understanding of your data and the table structure to avoid data type mismatches and ensure data integrity. Always exercise caution when modifying table structures, as it may impact existing data.
