Sql keeps throwing me a syntax error and I can't seem to figure out whats wrong.
ALTER TABLE `productList` ALTER COLUMN `ASIN` VARCHAR(32);
The error is the normal sql syntax error
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'VARCHAR(32)' at line 1
Try this:
ALTER TABLE `productList` MODIFY COLUMN `ASIN` VARCHAR(32);
The syntax to change the column name is
ALTER TABLE tablename MODIFY COLUMN new-column-definition
You need to use MODIFY COLUMN instead of ALTER COLUMN if you want to change the column definition.
https://dev.mysql.com/doc/refman/5.1/en/alter-table.html
It's modify, not alter column.
ALTER TABLE table_name
MODIFY column_name column_definition
[ FIRST | AFTER column_name ];

Please try the following:

This is a good read :)
When running
ALTER TABLE my_table modify column my_column int(10) NOT NULL DEFAULT 0;
I've got the error message:
Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'int(10) NOT NULL DEFAULT 0' at line 1.
How can this issue being fixed?
ALTER TABLE ... MODIFY COLUMN ... does not allow renaming the column; this is why the name of the column must be provided only once (the current name).
In order to rename the column (besides other changes you may want to operate on it, like changing its type) you have to use ALTER TABLE ... CHANGE COLUMN ... and provide the current and the new name of the column.
See the documentation page of the ALTER TABLE statement for more explanation and examples.
Try this code
ALTER TABLE my_table CHANGE mycolumn my_column INT( 10 ) NOT NULL DEFAULT '1';
I'm trying to add a gender column to my table with this query:
ALTER TABLE QRCodeUser ADD gender CHAR(1) enum('M','F') NOT NULL;
I get this error:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'enum('M','F') NOT NULL' at line 1
What's my mistake?
Try this (you dont need to specify the size, char(1) ) :
ALTER TABLE QRCodeUser ADD gender enum('M','F') NOT NULL;
Correct usage of syntax:
ALTER TABLE table_name ADD column_name enum(`field1`,`field2`,...);
Following statement gives me an error:
ALTER TABLE employee ALTER COLUMN Startdate datetime
Error:
Mysql error 1064
Mysql does not use ALTER COLUMN.
ALTER TABLE table_name
MODIFY COLUMN column_name datatype
Please Try the following
ALTER TABLE `DbName`.`table_name`
CHANGE COLUMN `column_name` `new_col_name` VARCHAR(250) NOT NULL DEFAULT '' ;

I get an error when using this command to alter my SQL table
Error message:
#1064 - You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the right
syntax to use near 'ALTER TABLE `report` AUTO_INCREMENT = 1, 30' at line 2`
Any idea of that?
So why would you say AUTO_INCREMENT=1,30 ?
It has to be one number, and not a comma separated list of numbers.
ALTER TABLE report AUTO_INCREMENT=1
or
ALTER TABLE report AUTO_INCREMENT=30
