How do I detect if a table exist in MySQL?
To detect the existence of a table, use the concept of INFORMATION_SCHEMA.TABLES. Following is the syntax −
select table_name from information_schema.tables where table_schema=database() and table_name=yourTableName;
To understand the above syntax, let us create a table −
mysql> create table DemoTable2032 -> ( -> ClientId int, -> ClientName varchar(20), -> ClientAge int, -> ClientCountryName varchar(20) -> ); Query OK, 0 rows affected (1.07 sec)
Here is the query to detect if a table exist in a database −
mysql> select table_name from information_schema.tables -> where table_schema=database() -> and table_name='DemoTable2032';
This will produce the following output −
+---------------+ | TABLE_NAME | +---------------+ | demotable2032 | +---------------+ 1 row in set (0.00 sec)
