问题 Is there any constraints to limit the number of records we can have in a table variable? If yes, what will be the maximum number records a table variable can hold? I have to write a stored procedure to process around 1000 records. Do I need to go with table variable or temporary table? 回答1: As such the official MSDN site where the Maximum Capacity Specifications for SQL Server there is no such upper limit defined for table variables because it depends on the database size and the free memory

问题 I am trying to figure out how to select half the records where an ID is null. I want half because I am going to use that result set to update another ID field. Then I am going to update the rest with another value for that ID field. So essentially I want to update half the records someFieldID with one number and the rest with another number splitting the update basically between two values for someFieldID the field I want to update. 回答1: In oracle you can use the ROWNUM psuedocolumn. I
