SELECT Statements
- Return all columns:
SELECT * FROM Customers
- Rename a column:
SELECT [CompanyName] AS MY_CompanyName FROM Customers
- Search data:
SELECT * FROM Customers WHERE Country = 'US';
- Return the number of items in a group:
SELECT COUNT(*) AS MyCount FROM Customers
- Return the number of unique items in a group:
SELECT COUNT(DISTINCT CompanyName) FROM Customers
- Summarize data:
SELECT CompanyName, MAX(Balance) FROM Customers GROUP BY CompanyName
- Sort a result set in ascending order:
SELECT City, CompanyName FROM Customers ORDER BY CompanyName ASC
- Restrict a result set to the specified number of rows:
SELECT City, CompanyName FROM Customers LIMIT 10
- Parameterize a query to pass in inputs at execution time. This enables you to create prepared statements and mitigate SQL injection attacks.
SELECT * FROM Customers WHERE Country = @param
Pseudo Columns
Some input-only fields are available in SELECT statements. These fields, called pseudo columns, do not
appear as regular columns in the results, yet may be specified as part of the WHERE clause. You can use pseudo columns to access additional features from Redis.
SELECT * FROM Customers WHERE MyPseudocolumn = [MyValue];
