Updating into string
The modifications made to each row affected by an UPDATE statement are determined by the list of assignments following the SET keyword.Each assignment specifies a to the left of the equals sign and a scalar expression to the right.This can also be used to change the column to NULL if the column has no default and is defined to allow null values.
Specifies the temporary named result set or view, also known as common table expression (CTE), defined within the scope of the UPDATE statement.
The CTE result set is derived from a simple query and is referenced by UPDATE statement.
An UPDATE statement is used to modify a subset of the values stored in zero or more rows of the database table identified by the qualified-table-name specified as part of the UPDATE statement.
If the UPDATE statement does not have a WHERE clause, all rows in the table are modified by the UPDATE.
The optional "OR action" conflict clause that follows the UPDATE keyword allows the user to nominate a specific constraint conflict resolution algorithm to use during this one UPDATE command.
Refer to the section entitled ON CONFLICT for additional information.Any characters not found in this code page are lost.Specifies that the default value defined for the column is to replace the existing value in the column.Columns that do not appear in the list of assignments are left unmodified.The scalar expressions may refer to columns of the row being updated.The OUTPUT clause is not supported in any DML statements that target remote tables or views. If the object being updated is the same as the object in the FROM clause and there is only one reference to the object in the FROM clause, an object alias may or may not be specified. Table2 (d1 int PRIMARY KEY NOT NULL, d2 int NOT NULL); GO INSERT INTO dbo. Table2 VALUES (1, 20), (2, 30); GO DECLARE abc CURSOR LOCAL FOR SELECT c1, c2 FROM dbo. Table1; GO Support for use of the READUNCOMMITTED and NOLOCK hints in the FROM clause that apply to the target table of an UPDATE or DELETE statement will be removed in a future version of SQL Server.Tags: Adult Dating, affair dating, sex dating
