Example

Assigns values to the fields of a struct.

Copy

<xsql-script name='struct_set_sample1'>
    <body>
        <struct.declare type='point2d'>
            <field name='x' type='double' />
            <field name='y' type='double' />
        </struct.declare>
        <set name='m_point'>
            <struct type='point2d'>
                <number>10</number>
                <number>20</number>
            </struct>
        </set>
        <println>X=<struct.get field='x'><m_point/></struct.get></println>
        <println>Y=<struct.get field='y'><m_point/></struct.get></println>
        <struct.set name='m_point'>
            <field name='x'>120</field>
            <field name='y'>160</field>
        </struct.set>
        <println>X=<struct.get field='x'><m_point/></struct.get></println>
        <println>Y=<struct.get field='y'><m_point/></struct.get></println>
    </body>
</xsql-script>

Screen printing would be the following:

Copy

X=10.0 Y=20.0 X=120.0 Y=160.0

You can observe how the content of the fields has been modified.

Example

Assigns and recuperates values of a struct through simple commands.

Copy

<xsql-script name='struct_set_sample1'>
    <body>
        <struct.declare type='point2d'>
            <field name='x' type='double' />
            <field name='y' type='double' />
        </struct.declare>
        <set name='m_point'>
            <struct type='point2d'>
                <number>10</number>
                <number>20</number>
            </struct>
        </set>
        <println>X=<m_point.x/></println>
        <println>Y=<m_point.y/></println>

        <set name='m_point.x'>120</set>
        <set name='m_point.y'>160</set>

        <println>X=<m_point.x/></println>
        <println>Y=<m_point.y/></println>
    </body>
</xsql-script>

Screen printing would be the following:

Copy

X=10.0 Y=20.0 X=120.0 Y=160.0

You can observe how the content of the fields has been modified.
