(ODBC Manager Library)
Description: | Builds SQL UPDATE statements using supplied field names and values. Made to be called as a subroutine, but will function as a called module. |
Returns: | Text |
Usage: | Script Only. |

Format: | \ODBCManager.BuildUpdate( TableName, UpdateFields, UpdateValues, SQLDataTypes, WhereFields, WhereOperators, WhereValues, WhereSQLDataTypes, WhereAND, dbType) |
Parameters: |
TableName | ||||||||||||
Required. Any expression for the name of the table to be updated. | ||||||||||||
UpdateFields | ||||||||||||
Required. May be a simple value or a one-dimensional array. Provides the field names to be updated | ||||||||||||
UpdateValues | ||||||||||||
Required. Any SQL data type. May be a simple value or a one-dimensional array. Provides the new values for the fields | ||||||||||||
SQLDataTypes | ||||||||||||
Required. Values indicating the data type of the update values. Should be a simple value or an array matching the UpdateFields parameter. Refer to Data Type Codes used in the ODBC Manager for a list of the numeric codes. | ||||||||||||
WhereFields | ||||||||||||
Required. Any expression or array of the field names for WHERE clause | ||||||||||||
WhereOperators | ||||||||||||
Required. May be a simple value or a one-dimensional array. Operators for WHERE clause | ||||||||||||
WhereValues | ||||||||||||
Required. May be a simple text value or a one-dimensional array of text. Values for WHERE clause | ||||||||||||
WhereSQLDataTypes | ||||||||||||
Required. Values indicating the data type of the insert values. Should be a simple value or an array matching the WhereFields parameter. Refer to Data Type Codes used in the ODBC Manager for a list of the numeric codes. | ||||||||||||
WhereAND | ||||||||||||
Required. Can be any expression that evaluates to a Boolean true or false. If set to true (non-zero) then the components of the WHERE clause are to be ANDed together. If false (0) an OR is used between the sub clauses. | ||||||||||||
dbType | ||||||||||||
Required numeric value, indicating the type of this DB connection.

Comments:
This module is a member of the ODBCManager Library, and must therefore be prefaced by \ODBCManager, as shown in "Format" above. Returns the SQL UPDATE statement as a text string unless binary parameters are involved, in which case an ODBCQuery structure is returned. The format of the structure is as follows:
ODBCQuery STRUCT [ QueryString; Parameters; ];
Example:
UpdateRecord [ If 1 GetUpdatedRecord; [ SubNames = New(2); SubValues = New(2); SubTypes = New(2); SubNames[0] = "TextVal"; SubNames[1] = "NumberVal"; SubTypes[0] = \ODBCManager\#SQL_VARCHAR; SubTypes[1] = \ODBCManager\#SQL_NUMERIC; SubValues[0] = "changed"; SubValues[1] = 110; Query = \ODBCManager.BuildUpdate("TestTable", SubNames, SubValues, SubTypes, "RecordName", "=", "rec1", Code\ODBCManager\#SQL_VARCHAR, 1, \ODBCManager\#dbType_MSAccess); Err = Invalid; Result = Invalid; Attrib = Invalid; ErrorMsg = Invalid; SQLState = Invalid; ErrorCode = Invalid; \ODBCManager.ExecuteQuery(&Err, Query, Conn1DSN, Invalid, Invalid, &Result, &Attrib, &ErrorMsg, &SQLState, &ErrorCode, 0, Invalid, 0, \ODBCManager\#dbType_MSAccess); ] ] GetUpdatedRecord [...
