SQL Where
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_name
FROM Store_Information
WHERE Sales > 1000
Result:
store_name
Los Angeles
