| 113 This File contains Key-Value-Pairs to define SQL-Statements. | |
| 114 All Queries will be handle using the Prepared-Statement-Syntax using "?" | |
| 115 to define an Place where an dynamic Value should be placed into the Statement. | |
| 116 | |
| 117 There is one special Implementation to support spatial access to the ArcSDE, | |
| 118 because the ArcSDE does not support the Access to spatial Objects using the | |
| 119 definition of the Simple Feature Specification for SQL of the OGC. | |
| 120 | |
| 121 It was necessary to implement this mechanism to simulate the Access. | |
| 122 | |
| 123 All Queries which contains the following Literals will be handle separate | |
| 124 using the ArcSDE-API. | |
| 125 | |
| 126 \begin{itemize} | |
| 127 \item ST\_ASTEXT(SHAPE): Will return the Geometry as an WellKnowText (WKT) | |
| 128 \item ST\_ASTEXT(RASTER): Will return the Raster in an readable Way. | |
| 129 \item INTERSECTS(SHAPE,"?"): Will only return the Elements which Geometry | |
| 130 intersects the given Geometry ("?" will be | |
| 131 replace with an WKT) | |
