Next, we might want to conditionally select the data from a table. For example, we may want to only retrieve stores with sales above $1,000. To do this, we use the WHERE keyword. The syntax is as follows:
SELECT "column_name"FROM "table_name"WHERE "condition"
For example, to select all stores with sales above $1,000 in Table Store_Information,
Table Store_Information:
-----------------------------------------------------------
store_name Sales Date
------------------------------------------------------------
Los Angeles $1500 Jan-05-1999
San Diego $250 Jan-07-1999
Los Angeles $300 Jan-08-1999
Boston $700 Jan-08-1999
------------------------------------------------------------
we key in,
SELECT store_nameFROM Store_InformationWHERE Sales > 1000;
Result:
store_name
Los Angeles
