问题 I'm writing an API in ASP.NET Core 3.1, using EF Core to access a SQL Server database. I have a function in the API that needs to call a stored procedure with several input parameters and an output parameter. A simplified version of this function is below.

问题 Update Sorry for the delay in responding. I was traveling yesterday when I sent that in. I am on version 5.6.

问题 This question already has an answer here : mysql Unknown column variable in the field list (1 answer) Closed 1 year ago .

问题 I have a simple table with some data: DROP TABLE IF EXISTS `MY_TABLE`; CREATE TABLE IF NOT EXISTS `MY_TABLE` ( `id` CHAR(40) CHARACTER SET 'utf8' COLLATE 'utf8_bin' NOT NULL, PRIMARY KEY (`id`) ); INSERT INTO `MY_TABLE` (`id`) VALUES (1); INSERT INTO `MY_TABLE` (`id`) VALUES (2); INSERT INTO `MY_TABLE` (`id`) VALUES (3); Now I have a procedure to retrieve this data ordering from a column.

问题 I need to write a procedure in Redshift that will write to a table, but the table name comes from the input string. Then I declare a variable that puts together the table name.
