Error renaming a column in MySQL

Question

How do I rename a column in table xyz? The columns are:

Manufacurerid, name, status, AI, PK, int

I want to rename to manufacturerid

I tried using PHPMyAdmin panel, but I get this error:

MySQL said: Documentation
#1025 - Error on rename of '.\shopping\#sql-c98_26' to '.\shopping\tblmanufacturer' (errno: 150)

Answer 1

Lone Ranger is very close... in fact, you also need to specify the datatype of the renamed column. For example:

ALTER TABLE `xyz` CHANGE `manufacurerid` `manufacturerid` INT;

Remember :

• Replace INT with whatever your column data type is (REQUIRED)
• Tilde/ Backtick (`) is optional

Answer 2

The standard Mysql rename statement is:

ALTER [ONLINE | OFFLINE] [IGNORE] TABLE tbl_name 
CHANGE [COLUMN] old_col_name new_col_name column_definition 
[FIRST|AFTER col_name]

for this example:

ALTER TABLE xyz CHANGE manufacurerid manufacturerid datatype(length)

Reference: MYSQL 5.1 ALTER TABLE Syntax

Answer 3

FOR MYSQL:

ALTER TABLE `table_name` CHANGE `old_name` `new_name` VARCHAR(255) NOT NULL;

FOR ORACLE:

ALTER TABLE `table_name` RENAME COLUMN `old_name` TO `new_name`;

EDIT

You can rename fields using:

ALTER TABLE xyz CHANGE manufacurerid manufacturerid INT

There is a syntax problem, because the right syntax to alter command is ALTER TABLE tablename CHANGE OldColumnName NewColunmName DATATYPE;

Answer 6

With MySQL 5.x you can use:

ALTER TABLE table_name
