MySQL Stored procedure to Generate-Extract Insert Statement

A lot of places I saw people asking for ways to generate Insert statements.

We do have GUI Tools which can extract insert statements for us readily. of the time I choose the MySQLDump way to generate insert statements.

mysqldump -uroot -ppassword –complete-insert –no-create-info DATABASE TABLENAME > TABLENAME.sql

But mind is very unstable and hungry, we don’t stop at one solution.
So to remove my mind’s starvation for the Stored Procedure way to extract Insert statement I created following routine.

As you can see this is really a simple procedure revolves around Information_schema mainly to get details of any table and then fires the simple sql query.

The procedure I named: InsGen
Input parameters:

in_db: Database name of the table for which you want to generate insert statements
in_table: Tabel name
in_file: complete file path [eg: C:/mysqlInserts.sql or /var/lib/data/mysqlInserts.sql]


CREATE DEFINER=`root`@`localhost` PROCEDURE `InsGen`(in_db varchar(20),in_table varchar(20),in_file varchar(100))

declare Whrs varchar(500);
declare Sels varchar(500);
declare Inserts varchar(2000);
declare tablename varchar(20);

set tablename=in_table;
select tablename;
# Comma separated column names – used for Select
select group_concat(concat(‘concat(\’”\’,',’ifnull(‘,column_name,’,””)’,',\’”\’)')) INTO @Sels from information_schema.columns where table_schema=in_db and table_name=tablename;

# Comma separated column names – used for Group By
select group_concat(‘`’,column_name,’`') INTO @Whrs from information_schema.columns where table_schema=in_db and table_name=tablename;

#Main Select Statement for fetching comma separated table values
set @Inserts=concat(“select concat(‘insert into “, in_db,”.”,tablename,” values(‘,concat_ws(‘,’,”,@Sels,”),’);’) from “, in_db,”.”,tablename,” group by “,@Whrs, ” INTO OUTFILE ‘”, in_file ,”‘”);

PREPARE Inserts FROM @Inserts;
EXECUTE Inserts;

END $$



Sample output:


Generate Inserts mysql


I have not considered each and every scenarios yet, but this works for normal tables and it does error if file exists.
My mind is no more hungry atleast in this regard.

I hope it helps.
