I have studied the technique of querying multiple keywords when I do a project, which is a technology in which it is used.
The "Separated string" stored procedure is to save the string of "jiangjs, shenxy, cheng" class to a table.
Create Procedure [Separate string]
(
@String nvarchar (1000), - Splitted strings
@Splitchar nvarchar (10) = ',', - Deliberate
@Tablename nvarchar (50), - Deposit Table Name
@Fieldname nvarchar (50) = '[id]' - stored in the field name
)
AS
- Separate strings in the open input
Declare @l int - the location of the first divided character
Declare @s int - the second separator position
Set @L = 0
Set @S = charindex (@splitchar, @string, @L)
While @L <= len (@string)
Begin
Declare @id nvarchar (50)
IF @S = 0 set @s = len (@string) 1 - If the last string is then the position of the second divided character is the length of this string plus one
Set @id = substring (@String, @L, @S - @L) - Value
Set @L = @S 1
Set @S = charindex (@splitchar, @string, @L)
IF LTRIM (RTRIM (@ID)) = '' Continue - Skip if it is an empty string
Declare @sql nvarchar (1000)
Set @SQL = 'INSERT INTO' @tablename '(' @fieldname ') VALUES (' '' @ID '') '
EXEC SP_EXECUTESQL @SQL
End
Go
