Updating dates in an update query

I left off the where statement at work while putting it into production, and watched in slow motion as the data was overwritten. Please never ever do it and always remember to back up your data before attempting data changing queries.When editing and posting a change to a Date Time column in MS SQL, the following statement is executed: UPDATE My Table SET "Start Date"='30/01/2015 ' WHERE "Id"=59; which leads to an error: /* SQL Error (3621): The conversion of a varchar data type to a datetime data type resulted in an out-of-range value The statement has been terminated.Take a look at how much better UPDATE looks: Our table before: followed by a column name set to a value.Then, you can use a comma and repeat that for as many columns as you want to update in those records.You'll find that SQL Server cannot process Date Time values with millisecond accuracy.

The following query reveals the milliseconds by using a CONVERT() function call: r4913 should fix some things on MSSQL: * Microsecond precision is now displayed in table structure editor, in column "Length/Set" * ...The reason your updates are not working, Ansgar, is not due to errors with Heidi or ISO format.The problem is caused by time precision in SQL Server.The SQL statement UPDATE is a crossbreed between INSERT and DELETE.It doesn’t exactly do either of them, but it has similar properties of each.
