mysql> select table_type, table_name from information_schema. tables −> where table_rows >= 1; Above, we have considered only the table that have 1 or more than 1 rows i.e. non-empty table.
To get a list of the tables in a MySQL database, use the mysql client tool to connect to the MySQL server and run the SHOW TABLES command. The optional FULL modifier will show the table type as a second output column.
SELECT * FROM yourTableName WHERE yourSpecificColumnName IS NULL OR yourSpecificColumnName = ' '; The IS NULL constraint can be used whenever the column is empty and the symbol ( ' ') is used when there is empty value.
'information_schema' should be holding the relevant details. You can try
SELECT table_type,
table_name
FROM information_schema.tables
WHERE table_rows >= 1;
to select from a selective database. You can also filter by TABLE_SCHEMA:
SELECT table_schema,
table_type,
table_name
FROM information_schema.tables
WHERE table_rows >= 1
AND TABLE_SCHEMA=?
The accepted answer never worked for me, information_schema table_rows have some very weird values.
This worked like a charm:
SHOW TABLE STATUS WHERE Rows > 0;
Docs for SHOW TABLE STATUS
Use database 'information_schema' and run
SELECT * FROM `TABLES` WHERE `TABLE_ROWS` > 0
this will give you all non-empty tables in the server for a certain database run
SELECT * FROM `TABLES` WHERE `TABLE_ROWS` > 0 AND `TABLE_SCHEMA` = 'database_name'
