- The INSERT INTO clause indicates that you intend to add a row to
- Following the INSERT INTO clause, the user specifies the name of
the table into which the data is to be inserted.
- When data values are being entered in the same order the
columns were created in
there is no need to list the column names following the INSERT INTO
clause. However, sometimes when a row is added, the correct ordering of
column values is not known. In those cases, the columns
being added must be listed following the table name in the order that
the values will be supplied.
- Following the keyword VALUES are the values to be added to one
row of a table. The entire row of values is placed within
parentheses. Each data value is separated from the next by a comma.
The first value corresponds to the first column in the table; the
second value corresponds to the second column in the table, and so on.
When the EMPLOYEE table is first created, it has no employee data
stored in it. Add the first record to the table, where the data
values we have are as follows:
EID = 101
ENAME = Aster, John A.
DEPT = MKT
RANK = STAFF
BENEFITS = FULL
SALARY = 32000
You can create a record containing these values by entering this
INSERT INTO EMPLOYEE
VALUES (101,'Aster, John A.','MKT','STAFF','FULL',32000) ;
Quotes are placed around character values so Texis can distinguish
data values from column names.
A new employee record gets added to the EMPLOYEE table, so that the
table now looks like this, if this were the only row entered:
EID ENAME DEPT RANK BENEFITS SALARY
101 Aster, John A. MKT STAFF FULL 32000
