SELECT Statements

A SELECT statement can consist of the following basic clauses.

  • SELECT
  • INTO
  • FROM
  • JOIN
  • WHERE
  • GROUP BY
  • HAVING
  • UNION
  • ORDER BY
  • LIMIT

SELECT Syntax

The following syntax diagram outlines the syntax supported by the SQL engine of the component:

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> ] 
  } [ , ... ]
  [ [  
      INNER | { { LEFT | RIGHT | FULL } [ OUTER ] } 
    ] 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 | NOT LIKE | IN | NOT IN | IS NULL | IS NOT NULL | AND | OR | CONTAINS | BETWEEN } [ <expression> ]
  } [ { AND | OR } ... ] 

Examples

  1. Return all columns:
    SELECT * FROM OEInvoices
  2. Rename a column:
    SELECT [ApprovedLimit] AS MY_ApprovedLimit FROM OEInvoices
  3. Cast a column's data as a different data type:
    SELECT CAST(AnnualRevenue AS VARCHAR) AS Str_AnnualRevenue FROM OEInvoices
  4. Search data:
    SELECT * FROM OEInvoices WHERE Allowpartialshipments = 'Yes';
  5. Return the number of items matching the query criteria:
    SELECT COUNT(*) AS MyCount FROM OEInvoices 
  6. Return the number of unique items matching the query criteria:
    SELECT COUNT(DISTINCT ApprovedLimit) FROM OEInvoices 
  7. Return the unique items matching the query criteria:
    SELECT DISTINCT ApprovedLimit FROM OEInvoices 
  8. Summarize data:
    SELECT ApprovedLimit, MAX(AnnualRevenue) FROM OEInvoices GROUP BY ApprovedLimit
    See Aggregate Functions for details.
  9. Retrieve data from multiple tables.
    SELECT * FROM OEInvoices INNER JOIN OEInvoices_InvoiceDetails ON OEInvoices.InvoiceUniquifier=OEInvoices_InvoiceDetails.InvoiceUniquifier
    See JOIN Queries for details.
  10. Sort a result set in ascending order:
    SELECT InvoiceUniquifier, ApprovedLimit FROM OEInvoices  ORDER BY ApprovedLimit ASC
  11. Restrict a result set to the specified number of rows:
    SELECT InvoiceUniquifier, ApprovedLimit FROM OEInvoices LIMIT 10 
  12. Parameterize a query to pass in inputs at execution time. This enables you to create prepared statements and mitigate SQL injection attacks.
    SELECT * FROM OEInvoices WHERE Allowpartialshipments = @param
See Explicitly Caching Data for information on using the SELECT statement in offline mode.

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 Sage 300.

    SELECT * FROM OEInvoices WHERE Query = 'Column3 > 100'
