Updating rows in mysql Free adult xxx phone chatlines

There are other issues but, I got confused with the table names.

bazz My answers are in one table (table_foobar), and does use a FK(question_id) to relate them to the questions table (table_questions).

Here is my example..normal update command would be: // question ID ranges from 1-20 // $questionid == 1, $member_id==1 UPDATE table_Foo Bar SET answer One='$ans1Val', answer Two='$ans2Val', answer Three='$ans3Val' WHERE member_id='$memberid' AND question_id='$questionid'; // $questionid == 2, $member_id==1 UPDATE table_Foo Bar SET answer One='$ans1Val', answer Two='$ans2Val', answer Three='$ans3Val' WHERE member_id='$memberid' AND question_id='$questionid'; ..

UPDATE table_Foo Bar SET answer One='yes', answer Two='no', answer Three='yes' WHERE member_id = 1 AND question_id = 1; UPDATE table_Foo Bar SET answer One='no', answer Two='no', answer Three='yes' WHERE member_id = 1 AND question_id = 2; UPDATE table_Foo Bar SET answer One='yes', answer Two='yes', answer Three='no' WHERE member_id = 1 AND question_id = 3; oh, absolutely!!

A requirement arises in many systems to update multiple SQL database rows.Thing is, there have been no concerns about normalization as I have had no problems with data insertion, querying results, reporting the answers, association of answers with members, etc!The only thing I am trying to solve is updating the database with one query instead of (1 to N) number of insert queries depending on how many "items" are listed.greetings all i have My SQL database named library contains a table named books with the attributes:name,amount,price,cat_id and i want to update all the names,amount,prices for specific cat_idso i used the following query:the code doesn't work properly it takes the values in the last row in the jtable and set them for all attributes with cat_id=1 meaning if you have 3 rows in the jtable named table_science which have cat_id=1 and the columns: name,amount,price abc,5,300 efg,6,400 mno,6,900 and when i exceute the update query all the fields in the database which have cat_id=1 would be set to mno,6,900 meaning that the table_science would be: mno,6,900 mno,6,900 mno,6,900 is there's an error in the code?

For small numbers of rows requiring updates, it can be adequate to use an UPDATE statement for each row that requires an update.
