I add this line for add ignore
to MySql database :
ALTER IGNORE cms_books_author name ADD UNIQUE(name)
but I get this error:
Error
SQL query:
ALTER IGNORE cms_books_author name ADD UNIQUE(name)
MySQL said: Documentation
#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 'efcms_books_author name ADD UNIQUE(name)' at line 1
Mysql version is : 5.6.20
how do I fix this error? Thank you.
syntax issues
- alter ignore missing the table keyword
- syntax should only include the name within the unique index not after the tablename
adjusted
ALTER IGNORE table cms_books_author ADD UNIQUE(name);
ALTER [ONLINE | OFFLINE] [IGNORE] TABLE tbl_name [alter_specification [, alter_specification] ...] [partition_options] ... alter_specification: table_options | ADD [CONSTRAINT [symbol]] UNIQUE [INDEX|KEY] [index_name] [index_type] (index_col_name,...) [index_option] ...
