Table Creation:
Creating table comes under Data Definition Language (DDL).
- The “CREATE TABLE” command is used to create a table by specifying the table name and then by listing the column in a single set of parentheses in the table.
- The “CREATE” command is employed for establishing databases on our platform by constructing tables in an already existing
database .
The Syntax for creating a table is as follows:
CREATE TABLE TABLE_NAME (
Column1 datatype,
Column2 datatype,
);

- Use SQL to complete the following exercises. Create a table named SALES_REP. The table has the same structure as the REP table shown in Figure 3-11 except the LAST _NAME column should use the VARCHAR data type and the COMMISSION and RATE columns should use the NUMBER data type. Execute the command to describe the layout and characteristics of the SALES_REP table.arrow_forwardReview the data for the TRIP table in Figure 1-5 in Chapter 1 and then review the data types used to create the TRIP table in Figure 3-39. Suggest alternate data types for at least two fields that currently have the CHAR data type and at least two fields that currently have the DECIMAL data type. Create but do not execute the SQL command to create the TRIP table using these alternate data types.arrow_forwardA new table has been requested to support tracking automated emails sent to customers. Create the table and add data as described below. Tablename: email_log Columns: emailid (numeric), emaildate (datetime), customer# (numeric) Primary key: emailid column, define as an Identity Column Add the following data rows and display resulting rows (if any errors occur, explain why the error is expected) Emaildate = current date, customer# = 1007 Emailid = specify to use the column default value, emaildate = current date, customer# = 1008 Emailid = 25, emaildate = current date, customer# = 1009arrow_forward
- Add a constraint to make sure the Rep_ID value entered in the BOOK_STORES table is a valid value contained in the STORE_REPS table. The Rep_ID columns of both tables were initially created as different datatypes. Does this cause an error when adding the constraint? Make table modifications as needed so that you can add the required constraint.arrow_forwardWhen must a comma be used in the SELECT clause of a query? a. when a field name is followed by a column alias b. to separate the SELECT clause and the FROM clause when only one field is selected c. Its never used in the SELECT clause. d. when listing more than one field name and the fields arent concatenated e. when an arithmetic expression is included in the SELECT clausearrow_forwardColonial Adventure Tours would like to increase the length of the START _LOCATION field in the TRIP table to 75 characters. Create but do not execute the SQL statement to change the length of the field to 75 characters.arrow_forward
