Parameters

db
Type: GeoEngine.Core.GXNetCDB
Database
line
Type: SystemInt32
Line Handle
r1_ch
Type: SystemInt32
Primary reference channel [<define>DB_LOCK_READONLY</define>]
r2_ch
Type: SystemInt32
Secondary reference channel [<define>DB_LOCK_READONLY</define>]
o_ch
Type: SystemInt32
Output channel [<define>DB_LOCK_READWRITE</define>]
r1_field
Type: SystemString
Primary reference field name in table
r2_field
Type: SystemString
Secondary reference field name in table
l_field
Type: SystemString
Lookup result field name in table
mode
Type: SystemInt32
<define>DU_LOOKUP</define>
close
Type: SystemDouble
CLOSE lookup distance. If 0.0, distance is calculated from secondary reference channel.
tb
Type: GeoEngine.Core.GXNetCTB
Table Object
Remarks
Fails if table does not contain requested fields. The nominal data sample spacing for the CLOSE options is calculated by finding the fiducial increment the - primary index channel for Lookup1C_DU; - secondary index channel for Lookup2C_DU, LookupIValC_DU and LookupRValC_DU
