Constructor Detail

JoinInfo

public JoinInfo(java.lang.String tableFrom,
                java.lang.String columnFrom,
                java.lang.String operator,
                java.lang.String tableTo,
                java.lang.String columnTo)

Constructs a Join definition of a JReport query.

Parameters:

tableFrom - The name of the table from which the join links.

columnFrom - The name of the column from which the join links.

operator - The String operator of the join .

tableTo - The name of the table to which the join links.

columnTo - The name of the column to which the join links.

JoinInfo

public JoinInfo(java.lang.String tableFrom,
                java.lang.String columnFrom,
                java.lang.String operator,
                java.lang.String tableTo,
                java.lang.String columnTo,
                boolean isSQL92,
                int outerJoin)

Constructs a Join definition of a JReport query.

Parameters:

tableFrom - The name of the table from which the join links.

columnFrom - The name of the column from which the join links.

operator - The String operator of the join .

tableTo - The name of the table to which the join links.

columnTo - The name of the column to which the join links.

isSQL92 - Indicates whether or not to apply SQL92 standard to the join sentence. There are two kinds of join formats: SQL92 and Use'+'.
The property is moved to JDBC connection.

outerJoin - Indicates the join type of the outer join. An outer join preserves these records in the result and replaces the missing values with nulls. JReport calls the join left (right) outer join if the records in the left (right) side table are preserved.
