20 Transact SQL - Select SELECT [ALL DISTINCT] <select_list> INTO [<new_table_name>] [FROM <table_name> [, <table_name2> [..., <table_name16>]] [WHERE <clause>] [GROUP BY <clause>] [HAVING <clause>] [ORDER BY <clause>] [COMPUTE <clause>] [FOR BROWSE] where <table_name> <view_name> = [[<database>.]<owner>.]{<table_name>. <view_name>.} <joined_table> = {<table_name> CROSS JOIN <table_name> <table_name> {INNER LEFT [OUTER] RIGHT [OUTER] FULL [OUTER]} JOIN <table_name> ON <search_conditions>} <optimizer_hints> One or more of the following, separated with a space: [INDEX = {<index_name> <index_id>}] [NOLOCK] [HOLDLOCK] [UPDLOCK] [TABLOCK] [PAGLOCK] [TABLOCKX] [FASTFIRSTROW]

21 T-SQL Select - Clauses WHERE <clause> = WHERE <search_conditions> GROUP BY <clause> = GROUP BY [ALL] <aggregate_free_expression> [[, <aggregate_free_expression>]...] [WITH {CUBE ROLLUP}] HAVING <clause> = HAVING <search_conditions> ORDER BY <clause> = ORDER BY {{<table_name>. <view_name>.}<column_name> <select_list_number> <expression>} [ASC DESC] [...{{<table_name16>. <view_name16>.}<column_name> <select_list_number> <expression>} [ASC DESC]] COMPUTE <clause> = COMPUTE <row_aggregate>(<column_name>) [, <row_aggregate>(<column_name>)...] [BY <column_name> [, <column_name>]...]

22 T-SQL Select Example SELECT O_ID AS ORDER_ID, SUM(PRICE * QNT) AS PRICE FROM SPARTS, STORE WHERE PART_ID = PART GROUP BY O_ID

23 T-SQL Table Creating Tables CREATE TABLE [database.[owner].]table_name ({col_name column_properties [constraint [constraint [...constraint]]] [[,] constraint]} [[,] {next_col_name next_constraint}...]) CREATE TABLE [dbo].[store] ( [PART_ID] [int] IDENTITY (1, 1) NOT NULL, [NAME] [char] (10) NOT NULL, [PRICE] [money] NOT NULL, [WARANTY] [int] NOT NULL CONSTRAINT [DF_STORE_WARANTY] DEFAULT (1), [QUANTITY] [int] NOT NULL CONSTRAINT [DF_STORE_QUANTITY] DEFAULT (1), CONSTRAINT [PK_STORE] PRIMARY KEY NONCLUSTERED ( [PART_ID] ) ON [PRIMARY] ) ON [PRIMARY] GO

24 T-SQL View Views CREATE VIEW [owner.]view_name [(column_name [, column_name]...)] [WITH ENCRYPTION] AS select_statement [WITH CHECK OPTION] CREATE VIEW dbo.config_guarancy AS SELECT CONF_ID, CUSTOMER, DATEADD(MM, WARANTY, DATE_ASSEM) AS GUARANCY FROM CONFIGURATIONS

25 T-SQL DML Insert statement insert [into] table_name [(column_list)] {values (expression [,expression]...} {select statement} Update update table_name set column_name1 = {expression1/null (select statement)} [,column_name2 = {expression2/null (select statement)}...] from table_name [where search_conditions] Delete statement delete table_name [from table_name, table_name...] [where search_conditions] or truncate table table_name

26 T-SQL DML Example CREATE PROCEDURE NEW_CONFIG INT) AS INSERT INTO CONFIGURATIONS (ID1, ID2, ID3, ID4, ID5, ID6, ID7, ID8, ID9, ID10, UPDATE STORE SET QUANTITY = QUANTITY - 1 WHERE PART_ID OR PART_ID OR PART_ID OR PART_ID OR PART_ID OR PART_ID OR PART_ID OR PART_ID OR PART_ID OR PART_ID GO

27 T-SQL Store Procedure CREATE PROCEDURE GUARANCY_CHECK INT) AS INT = GUARANCY FROM CONFIG_GUARANCY WHERE CONF_ID = GETDATE()) < 0 UPDATE REPAIR SET PRICE = 0 WHERE CONFIGURATION GO
