too long

i am getting internal server error while running this query

mysql_query("select * from table_name where PARTY LIKE '%NIXON%' group by 1_FROM_2_TO,INSTR_,PARTY limit 1770");

but i will get result when change the limit to 1765

mysql_query("select * from table_name where PARTY LIKE '%NIXON%' group by 1_FROM_2_TO,INSTR_,PARTY limit 1765");

what is the problem here? thanks in advance.

See your Error Log. it may be a mysql problem. check the version of your mysql.

Try this,

mysql_query("select * from table_name where PARTY LIKE '%NIXON%' group by 
         1_FROM_2_TO,INSTR_,PARTY limit 0, 1770");

Also, see your apache error log, you will get the Error from mysql_query You can use die if mysql_query() fails, like

$res=mysql_query("select * from table_name where PARTY LIKE '%NIXON%' group by 
         1_FROM_2_TO,INSTR_,PARTY limit 0, 1770") or die(mysql_error());

Enabling error_reporting can be used to see the errors like notices, or warnings
