Method Detail

getPkValues

public Map<String,List<Object>> getPkValues()
                                     throws SQLException

1. If the insert columns are not empty and do not contain any pk columns, it means that there is no pk value in the insert rows, then all the pk values should come from auto-increment.

2. The pk value exists in insert rows. The possible situations are:

• The insert columns are empty: all pk values can be obtained from insert rows
• The insert columns contain at least one pk column: first obtain the existing pk value from the insert rows, and other from auto-increment

Specified by:

getPkValues in interface InsertExecutor

Returns:

Map<String, List<Object>>

Throws:

SQLException - the sql exception

containsAnyPk

public boolean containsAnyPk()

Whether the insert columns contain any pk columns

Returns:

true: contain at least one pk column. false: do not contain any pk columns

getPkValuesByColumn

public Map<String,List<Object>> getPkValuesByColumn()
                                             throws SQLException

Description copied from interface: InsertExecutor

get primary key values by insert column.

Specified by:

getPkValuesByColumn in interface InsertExecutor

Returns:

pk values by column

Throws:

SQLException - the sql exception

getPkValuesByDefault

                                              throws SQLException

Deprecated.

get primary key values by default

Specified by:

getPkValuesByDefault in interface Defaultable

Returns:

Specified by:

getPkValuesByDefault in interface Defaultable

Parameters:

pkKey - the pk key

Returns:

the primary values

Throws:
