    | { 
        <expression> [ [ AS ] <column_reference> ] 
        | { <table_name> | <correlation_name> } .* 
      } [ , ... ] 
  }
  [ INTO csv:// [ filename= ] <file_path> [ ;delimiter=tab ] ]
  { 
    FROM <table_reference> [ [ AS ] <identifier> ] 
  }
  [ WHERE <search_condition> ]
} | SCOPE_IDENTITY() 

  <expression> ::=
    | <column_reference>
    | @ <parameter> 
    | ?
    | COUNT( * | { [ DISTINCT ] <expression> } )
    | { AVG | MAX | MIN | SUM | COUNT } ( <expression> ) 
    | NULLIF ( <expression> , <expression> ) 
    | COALESCE ( <expression> , ... ) 
    | CASE <expression>
        WHEN { <expression> | <search_condition> } THEN { <expression> | NULL } [ ... ]
    [ ELSE { <expression> | NULL } ]
      END 
    | <literal>
    | <sql_function> 

  <search_condition> ::= 
    {
      <expression> { = | < | > | IN } [ <expression> ]
    } [ { AND | OR } ... ]

Examples

  1. Return all columns:
    SELECT * FROM Payments
  2. Rename a column:
    SELECT "DeviceName" AS MY_DeviceName FROM Payments
  3. Cast a column's data as a different data type:
    SELECT CAST(InclusiveTaxMoneyAmount AS VARCHAR) AS Str_InclusiveTaxMoneyAmount FROM Payments
  4. Search data:
    SELECT * FROM Payments WHERE Id = 'Jq74mCczmFXk1tC10GB';
  5. The Square APIs support the following operators in the WHERE clause: =, <, >, IN.
    SELECT * FROM Payments WHERE Id = 'Jq74mCczmFXk1tC10GB';
