An example in My SQL: assuming you've created the For our purposes, if you're using a GUI, you're better off figuring out how to add rows via button-clicking.

It's not as nice as a spreadsheet, but for bulk data entry, you may have bigger needs than what can be done solely with just the GUI or even queries.

In the following rows of item table, 'value' column which is marked with red rectangle will be updated.

PHP Script Sample Output: Multiple Updates in My SQL Sample table: table1 Problem If you want to update the val1 with 5,8 and 7 for concerned id 1,3 and 4 and the other val1 will remain same and the val2 will be updated with 13 and 5 for the concerned id 2 and 4 and the other will remain same, the following update statement can be used by using IF and CASE.

I'm talking about the actual query that the PHP script would run once it's put in the values of the variables.so here is an edited version of the query being run.You have an error in your SQL syntax; check the manual that corresponds to your My SQL server version for the right syntax to use near ' TABLE tablename SET column2=random field, column3=1, column4=87517, column5=1, column6=sell, ' at line 1 Query: UPDATE TABLE tablename SET column2=random field, column3=1, column4=87517, column5=1, column6=sell, column7=big description field is boring to fill out., column8=key field who cares, column9=nother key field jeeze, column10=random unneeded field, column11=boring blah blah, column12=, column13=, column14=, column15=, column16=, column17= WHERE column1=14 phpmyadmin gives error 1064 I don't get it all the information being updated was just entered into an insert query with the other 2 columns not used in the update query the datetime and a counter field and it works just fine, but when its run in an update query it keeps stopping at the sql syntax error.this is my table structure if this might have something to do with it.
