SELECT Syntax
The following syntax diagram outlines the syntax supported by the Oracle Sales Cloud adapter:
SELECT {
[ TOP <numeric_literal> | DISTINCT ]
{
*
| {
<expression> [ [ AS ] <column_reference> ]
| { <table_name> | <correlation_name> } .*
} [ , ... ]
}
[ INTO csv:// [ filename= ] <file_path> [ ;delimiter=tab ] ]
{
FROM <table_reference> [ [ AS ] <identifier> ]
} [ , ... ]
[
JOIN <table_reference> [ ON <search_condition> ] [ [ AS ] <identifier> ]
] [ ... ]
[ WHERE <search_condition> ]
[ GROUP BY <column_reference> [ , ... ]
[ HAVING <search_condition> ]
[ UNION [ ALL ] <select_statement> ]
[
ORDER BY
<column_reference> [ ASC | DESC ] [ NULLS FIRST | NULLS LAST ]
]
[
LIMIT <expression>
[
{ OFFSET | , }
<expression>
]
]
} | 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> { = | > | < | >= | <= | <> | != | LIKE | AND } [ <expression> ]
} [ { AND | OR } ... ]
Examples
- Return all columns:
SELECT * FROM Opportunities
- Rename a column:
SELECT "Name" AS MY_Name FROM Opportunities
- Cast a column's data as a different data type:
SELECT CAST(WinProb AS VARCHAR) AS Str_WinProb FROM Opportunities
- Search data:
SELECT * FROM Opportunities WHERE CreatedBy = 'Jack'
- The Oracle Sales Cloud APIs support the following operators in the WHERE clause: =, >, <, >=, <=, <>, !=, LIKE, AND.
SELECT * FROM Opportunities WHERE CreatedBy = 'Jack';
- Return the number of items matching the query criteria:
SELECT COUNT(*) AS MyCount FROM Opportunities
- Return the number of unique items matching the query criteria:
SELECT COUNT(DISTINCT Name) FROM Opportunities
- Return the unique items matching the query criteria:
SELECT DISTINCT Name FROM Opportunities
- Sort a result set in ascending order:
SELECT OptyId, Name FROM Opportunities ORDER BY Name ASC
