Count(*) from tablename
Question
SIMULATION -
What word is missing from the following SQL statement?
__________ count(*) from tablename;
(Please specify the missing word using lower-case letters only.)
Explanations
select
The missing word in the given SQL statement is "SELECT".
The complete SQL statement is:
SELECT count(*) from tablename;
The "SELECT" statement is used to retrieve data from one or more tables in a database. In this case, we are using the "SELECT" statement to retrieve the count of all records in the "tablename" table. The "count(*)" function is used to count the number of rows in a table.
So, the correct SQL statement to count the number of records in the "tablename" table is:
SELECT count(*) from tablename;
It's worth noting that SQL is case-insensitive, meaning that "SELECT" and "select" are interchangeable. However, it is a common convention to write SQL keywords in uppercase letters for better readability and clarity.
