SQL SELECT WHERE Clause
Using the SELECT WHERE clause, we can filter a query based on certain conditions. For example, if we want to filter records by word matches, we use the LIKE operator and wildcard characters.
Syntax:
SELECT column1, column2, …
FROM table_name
WHERE condition;
Explanation: This query is used for searching data where the condition is true in a mentioned column of a table.
‘LIKE’ operator
The ‘LIKE’ operator is commonly used for matching patterns in SQL queries. We can use ‘%’ as a wildcard to represent any sequence of characters.
Syntax:
SELECT column1, column2, …FROM table_nameWHERE column_name LIKE ‘%word%’;
The ‘%word%’ will match any value that contains the word ‘word’ and the ‘%’ before and after makes sure that the mentioned word can occur at any position(beginning, middle or end).
SQL SELECT WHERE Field Contains Words
The SQL SELECT WHERE field Contains Words” in SQL is used to find data with specific words in it. It helps us to find patterns in text fields. One more way to do this is by using full-text search, which searches entire blocks of text to find what we need.
In simple words, we can say SQL gives us ways to find data based on words or phrases in fields which makes it easier to get the required information.
