SYSADMIN.checkSortOrder

This stored procedure queries the specified column, sorts data using a DBMS native ORDER BY, sorts the same data internally in the Data Virtuality Server, and returns differences between the two result sets.

SQL

SYSADMIN.checkSortOrder(IN schemaName string NOT NULL, IN tableName string NOT NULL, IN columnName string NOT NULL, IN maxRows integer)

Example

SQL

CALL SYSADMIN.checkSortOrder('test_tables', 'test_e', 'e', 5)

SYSADMIN.clearResultSetCache

This procedure cleans the result set cache.

SQL

SYSADMIN.clearResultSetCache()

SYSADMIN.clearResultCache is available since v3.7

SYSADMIN.getJwtToken

This procedure calculates the JSON Web Token.

SQL

SYSADMIN.getJwtToken(IN payload clob NOT NULL, IN privateKeyPath blob NOT NULL, IN encryptionAlgorithm string, IN jwtHeader clob, OUT token string RESULT)

It supports different ways of providing a private key:

Text in PEM format (in base64);
Path for a file with a private key in PEM or DER format;
Byte stream from a file data source.

It supports the following algorithms:

RS256 (default)
RS384
RS512
PS256
PS384
PS512
ES256
ES384
ES512

Examples

SQL

SYSADMIN.md5

This procedure returns the md5 hash value for a given parameter.

CODE

SYSADMIN.md5(IN param string, OUT hash string)

Example

SQL

SELECT hash FROM (CALL SYSADMIN.md5(1)) AS a WHERE hash=ucase('c4ca4238a0b923820dcc509a6f75849b');

md5 accepts an empty/null string or whitespace-like tab:

For null value, there is going to be just an empty string as a result;
For non-null values (empty string, string with whitespaces or tabs, etc.), md5 will be calculated and returned as a result.

Examples

SQL

SELECT hash FROM (CALL SYSADMIN.md5('')) AS a;
SELECT hash FROM (CALL md5(null)) AS a;

SYSADMIN.reservedWords

This procedure returns a list of keywords needed for code completion. It includes clauses, data types, functions, arithmetic operation signs, etc.

SQL

SYSADMIN.reservedWords(OUT keyword string NOT NULL, OUT type string NOT NULL)

SYSADMIN.reservedWords procedure is available since v3.2

SYSADMIN.sendOracleADWCWallet

This procedure uploads a wallet file for an Oracle ADWC data source.

SQL

SYSADMIN.sendOracleADWCWallet(IN trustStorePassword string NOT NULL, IN base64Wallet string NOT NULL)

SYSADMIN.setRemark

This procedure sets a remark for a given table, column, procedure, or view.

SQL

SYSADMIN.setRemark(IN name string NOT NULL, IN remark string NOT NULL)

Examples

SQL

CALL "SYSADMIN.setRemark" (
    "name" => 'views.employee'
    ,"remark" => 'here remark was set for the view/proc'
) ;;

CALL "SYSADMIN.setRemark" (
    "name" => 'adv.contacttype'
    ,"remark" => 'here remark was set for the table'
) ;;

CALL "SYSADMIN.setRemark" (
    "name" => 'adv.contact.FirstName'
    ,"remark" => 'here remark was set for the column'
) ;;

The setRemark() procedure can be used with OPTION $NOFAIL. Here is an example of this:

SQL

CALL "SYSADMIN.setRemark" (
    "name" => 'adv.contact.FirstName'
    ,"remark" => 'here remark was set for the column'
) OPTION $NOFAIL;;

The Data Virtuality Exporter will not export remarks set on physical data sources, as well as those set on tables, views or procedures stored in such a data source. Remarks set on virtual schemas and objects will be exported.

Furthermore, the Data Virtuality Exporter adds OPTION $NOFAIL to all setRemark() system procedures.

SYSADMIN.sleep

This procedure pauses the execution of the current process for the specified time in milliseconds.

SQL

SYSADMIN.sleep(IN millis long NOT NULL))

Example

In this example, the sleep time is set to 5 seconds:

SQL

CALL SYSADMIN.sleep(5000)
