In Java, there is a 'switch - case' statement which is similar to MySQL's 'case - when' statement. switch (N) { // assume N is an integer variable case 1: System.out.println("One"); break; case 2: case 3: System.out.println("Two or Three"); ...

The[mysqld]or[mysqld_safe]groups can be used for common options read by all instances ofmysqldormysqld_safe. You can specify a--defaults-file=file_nameoption to use a different configuration file for that instance, in which case the[mysqld]or[mysqld_safe]groups from that file are used...
Executing a multiple-statement string can produce multiple result sets or row-count indicators. Processing these results involves a different approach than for the single-statement case: After handling the result from the first statement, it is necessary to check whether more results exist and process...
In that case its not performing very efficiently. Can anybody suggest anything ? I have also shared the Explain result of the query being generated. However, sharing the Table structure won't be a good idea as some tables have columns more than 50. 1 SIMPLE sp ALL NULL NULL NULL NULL ...
() function, unless functions will be extended to return multiple rows anytime soon. An ordered set of ALL the IDs of the last insertion is obviously much more generally helpful than either the first OR last of that set. In my case, it would allow more efficient, mass insertions/updates ...
The query joins many tables, and the columns in the ORDER BY are not all from the first nonconstant table that is used to retrieve rows. (This is the first table in the EXPLAIN output that does not have a const join type.) So for my case, given that the two columns I'm ordering...
Hi, Just for everybody to know, that our case was discussed internally with MySQL as I could not reveal the code example in public. MySQL documentation has been updated to contain restrictions and we have changed our setup to single primary mode. Our issue is still possible to be reproduced...
