This article mainly introduces "the realization method of table name and field name as variable in mssql stored procedure". In daily operation, I believe that many people have doubts about the realization method of table name and field name as variable in mssql stored procedure. Xiaobian consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubt that "table name and field name are variables in mssql stored procedure". Next, please follow the editor to study!

Do not use dynamic statements to report errors directly

The copy code is as follows: alter proc testpapers as begin declare @ tems nvarchar (max), @ zidaun nvarchar (max) set @ tems=select * from @ tems order by @ zidaun exec (@ tems) end exec testpapers

Message 156level 15, state 1, procedure testpapers, line 1 keyword 'select'' there is a syntax error. Message 1087, level 15, state 2, procedure testpapers, line 1 must declare the table variable "@ tems". First of all, to make the table name or field a variable, the copy code for dynamic statement errors is as follows: alter proc testpapers as begin declare @ tems nvarchar (max), @ zidaun nvarchar (max) set @ tems='select * from @ tems order by @ zidaun'; exec (@ tems) end exec testpapers

Message 1087, level 15, status 2, line 1 must declare the table variable "@ tems". The correct copy code for writing table and field names into exec is as follows: alter proc testpapers as begin declare @ startRow nvarchar (max), @ tems nvarchar (max), @ zidaun nvarchar (max) set @ startRow='temp' set @ tems='select * from'; set @ zidaun='p_id'; exec (@ tems+@startRow+' order by'+ @ zidaun) end exec testpapers

At this point, the study on "the implementation of table names and field names as variables in mssql stored procedures" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
