1. Creating Tables Create a new table by defining the column structure.3
Creating Tables
Create a new table by defining the column structure.
Create a new table by copying column structure from an existing table.
Create a new table and add data using a single query.
Load data into a table.

2. Creating Tables with SQL
Multiple techniques are used to create tables and insert data into tables with SQL.
Method
Syntax
Result 1
CREATE TABLE table-name (column-name type(length) <, ...column-name type(length)>);
Create an empty table by manually specifying all column attributes. 2
CREATE TABLE table-name LIKE old-table-name;
Create an empty table by copying column attributes from an existing table using a LIKE clause. 3
CREATE TABLE table-name AS query-expression;
Create a table and add data all in one step, using a query.

3. Creating Tables
Method 1: Define the columns. General form of the CREATE TABLE statement:
CREATE TABLE table-name (column-name type(length) <, ...column-name type(length)> );

4. Method 1: Defining Columns
The table definition is enclosed in parentheses. Individual column definitions are separated by commas.
proc sql;
create table Discounts
(Product_ID num format=z12.,
Start_Date date,
End_Date date,
Discount num format=percent.);
quit;
proc contents data=discounts;run;
Name the new table.
Define the columns.

5. Method 1: Defining Columns
For ANSI compliance, PROC SQL accepts the following data types in table definitions:
ANSI Type
Resulting SAS Type
Default Length
Default Format
CHAR(n)
Character 8
$w.
VARCHAR
INTEGER
Numeric
BEST.
SMALLINT
DECIMAL
NUMERIC
FLOAT
REAL
DOUBLE PRECISION
DATE
DATE.

6. Method 1: Defining Columns
proc sql;
create table Testing_Types
(Char_Column char(4),
Varchar_Column varchar,
Int_Column int,
SmallInt_Column smallint,
Dec_Column dec,
Num_Column num,
Float_Column float,
Real_Column real,
Date_Column date,
Double_Column double precision);
quit;
proc contents data=testing_types;run;

7. Creating Tables Method 2: Copy the table structure.
CREATE TABLE table-name-2 LIKE table-name-1;

8. Method 2: Copying Table Structure
proc sql;
create table work.New_Sales_Staff like orion.Sales ;
quit;
proc contents data=new_sales_staff;
run;

9. Creating Tables (Review)
Method 3: Create and populate a table with an SQL query.
CREATE TABLE table-name AS query-expression;

10. Method 3: Create and Populate a Table with an SQL Query (Review)
proc sql;
create table work.Melbourne as
select Employee_Name as Name,Salary
from orion.Staff as s,
orion.Employee_addresses as a
where s.Employee_ID=a.Employee_ID
and City ="Melbourne";
quit;
proc contents data=melbourne;run;

11. Adding Data to a Table, the INSERT Statement
The INSERT statement can be used to add data to an empty table, or to append data to a table that already contains data, using one of three methods.
Method
Syntax
Description A
INSERT INTO table-name SET column-name=value,
column-name=value,...;
One clause per row using column-value pairs B
INSERT INTO table-name
<(column list)> VALUES (value,value,...);
One clause per row using positional values C
INSERT INTO table-name <(column list)> SELECT columns FROM table-name;
A query returning multiple rows, and based on positional values

12. Create the example table, discounts
proc sql;
create table Discounts
(Product_ID num format=z12.,
Start_Date date,
End_Date date,
Discount num format=percent.);
quit;
proc contents data=discounts;run;

13. Method A: Adding Data with a SET Clause
The SET clause requires that you add data using column name–value pairs:
proc sql;
insert into Discounts
set Product_ID= ,
Start_Date='01MAR2007'd,
End_Date='15MAR2007'd,Discount=.33
set Product_ID= ,
Start_Date='16MAR2007'd,
End_Date='31MAR2007'd, Discount=.15 ;
quit;
proc print data=discounts;run;

14. Method B: Adding Data with a VALUES Clause
proc sql;
create table Discounts
(Product_ID num format=z12.,
Start_Date date,
End_Date date,
Discount num format=percent.) ;
insert into Discounts
values ( ,'01MAR2007'd,
'15MAR2007'd,.33)
values ( ,'16MAR2007'd,
'31MAR2007'd,.15)
select * from discounts;
quit;
The VALUES clause adds data to the columns in a single row of data. The VALUES clause must produce values in the same order as the INSERT INTO statement column list.

15. Method B: Adding Data with a VALUES Clause
proc sql;
create table Discounts
(Product_ID num format=z12.,
Start_Date date,
End_Date date,
Discount num format=percent.) ;
insert into Discounts
(Start_Date,End_Date, Product_ID, Discount)
values ('01MAR2007'd,'15MAR2007'd, ,.33)
values ('16MAR2007'd,'31MAR2007'd, ,.15)
select * from discounts;
quit;
Optionally, the INSERT statement can list the columns into which data is to be inserted, in the order in which the VALUES clause will provide the data.

16. Method C: Adding Data with a Query
proc sql;
create table Discounts
(Product_ID num format=z12.,
Start_Date date,
End_Date date,
Discount num format=percent.) ;
insert into Discounts
(Product_ID,Discount,Start_Date,End_Date)
select distinct Product_ID,.35,
'01MAR2007'd,'31mar2007'd
from orion.Product_Dim
where Supplier_Name contains
'Pro Sportswear Inc'
select * from discounts;
quit;
Query results are inserted positionally. The query must produce values in the same order as the INSERT statement column list.
