Detailed Description

provides an outbound data mapper to a Table with SqlUtil select hash as a asource

Member Function Documentation

◆ constructor() [1/2]

TableMapper::SqlStatementOutboundMapper::constructor	(	SqlUtil::AbstractTable	source,
		*hash< auto >	sh,
		hash< auto >	mapv,
		*hash< auto >	opts
	)

builds the object based on an optional hash providing field mappings, data constraints, and optionally custom mapping logic

The source statement is also scanned using Qore::SQL::AbstractSQLStatement and column definitions are used to update the source record specification.

Parameters

source	the source table object. A `sh` select hash is applied to this table
sh	a SqlUtil select hash
mapv	a optional hash providing overrides for the default 1:1 input to output field mappings; each hash key is the name in lower case of the output column in the target table; each value is either True (meaning no translations are done; the data is copied 1:1) or a hash describing the mapping; see Mapper Specification Format for detailed documentation for this option
opts	an optional hash of options for the mapper; see Mapper Options for a description of valid mapper options plus the following options specific to this object: `"select_block"`: for size of the batch returned from TableMapper::AbstractSqlStatementOutboundMapper::getData() or AbstarctSqlStatementOutboundMapper::getDataRows()

Exceptions

MAP-ERROR

◆ constructor() [2/2]

TableMapper::SqlStatementOutboundMapper::constructor	(	SqlUtil::Table	source,
		*hash< auto >	sh,
		hash< auto >	mapv,
		*hash< auto >	opts
	)

builds the object based on an optional hash providing field mappings, data constraints, and optionally custom mapping logic

The source statement is also scanned using Qore::SQL::SQLStatement and column definitions are used to update the source record specification.

Parameters

source	the source table object. A `sh` select hash is applied to this table
sh	a SqlUtil select hash
mapv	a optional hash providing overrides for the default 1:1 input to output field mappings; each hash key is the name in lower case of the output column in the target table; each value is either True (meaning no translations are done; the data is copied 1:1) or a hash describing the mapping; see Mapper Specification Format for detailed documentation for this option
opts	an optional hash of options for the mapper; see Mapper Options for a description of valid mapper options plus the following options specific to this object: `"select_block"`: for size of the batch returned from TableMapper::AbstarctSqlStatementOutboundMapper::getData() or AbstarctSqlStatementOutboundMapper::getDataRows()

Exceptions

MAP-ERROR

◆ getTable()

SqlUtil::AbstractTable TableMapper::SqlStatementOutboundMapper::getTable ( )

returns the underlying SqlUtil::AbstractTable object

Returns: SqlUtil::AbstractTable provided in constructor

◆ getTableName()

string TableMapper::SqlStatementOutboundMapper::getTableName ( )

returns the table name

Returns: string with main table name

◆ optionKeys()

hash<auto> TableMapper::SqlStatementOutboundMapper::optionKeys ( )

returns a list of valid constructor options for this class (can be overridden in subclasses)

Returns: a list of valid constructor options for this class (can be overridden in subclasses)
