JET_OBJECTLIST Structure

The JET_OBJECTLIST structure traverses a temporary table that was created with JetGetObjectInfo. Each row in the temporary table describes an object in the database.

    typedef struct {
      unsigned long cbStruct;
      JET_TABLEID tableid;
      unsigned long cRecord;
      JET_COLUMNID columnidcontainername;
      JET_COLUMNID columnidobjectname;
      JET_COLUMNID columnidobjtyp;
      JET_COLUMNID columniddtCreate;
      JET_COLUMNID columniddtUpdate;
      JET_COLUMNID columnidgrbit;
      JET_COLUMNID columnidflags;
      JET_COLUMNID columnidcRecord;
      JET_COLUMNID columnidcPage;
    } JET_OBJECTLIST;

Members

cbStruct

The size of the structure, in bytes. The API call will update this field, so the caller should ensure that this value matches sizeof( JET_INDEXLIST ).

tableid

The table identifier of the temporary table that was created. The caller must contain code that will close the table.

cRecord

The number of records in the temporary table that was created.

columnidcontainername

The column identifier of the name of the type of container.

The only containers that are currently supported are tables. This column is a JET_coltypText.

columnidobjectname

The column identifier of the name of the object.

This column is a JET_coltypText.

columnidobjtyp

The column identifier of the type of the object. The only containers that are currently supported are tables, so this field will be JET_objtypTable.

This column is a JET_coltypLong.

columniddtCreate

Obsolete. Do not use.

columniddtUpdate

Obsolete. Do not use.

columnidgrbit

The column identifier of the grbits that are applicable to the object. For a list of applicable grbits, see JET_TABLECREATE.

This column is a JET_coltypLong.

columnidflags

The column identifier of the flags that are applicable to the object. For a list of applicable flags, see JET_OBJECTINFO.

This column is a JET_coltypLong.

columnidcRecord

The column identifier of the number of records that are present in the table that is named in columnidobjectname.

This column is a JET_coltypLong.

columnidcPage

The column identifier of the number of pages the object uses.

This column is a JET_coltypLong.

Remarks

Each row in the temporary table corresponds to an object in the database.

When the temporary table is created with the InfoLevel parameter in the JetGetObjectInfo function set to JET_ObjInfoListNoStats, the columns identified by columnidcRecord and columnidcPage will not contain meaningful information.

Currently, only information about tables will be in the temporary table.
