-** This function returns a pointer to a nul-terminated string in memory |
-** obtained from sqlite3DbMalloc(). If sqlite3.nVdbeExec is 1, then the |
-** string contains a copy of zRawSql but with host parameters expanded to |
-** their current bindings. Or, if sqlite3.nVdbeExec is greater than 1, |
-** then the returned string holds a copy of zRawSql with "-- " prepended |
-** to each line of text. |
-** |
-** If the SQLITE_TRACE_SIZE_LIMIT macro is defined to an integer, then |
-** then long strings and blobs are truncated to that many bytes. This |
-** can be used to prevent unreasonably large trace strings when dealing |
-** with large (multi-megabyte) strings and blobs. |
-** |
-** The calling function is responsible for making sure the memory returned |
-** is eventually freed. |
-** |
-** ALGORITHM: Scan the input string looking for host parameters in any of |
-** these forms: ?, ?N, $A, @A, :A. Take care to avoid text within |
-** string literals, quoted identifier names, and comments. For text forms, |
-** the host parameter index is found by scanning the prepared |
-** statement for the corresponding OP_Variable opcode. Once the host |
-** parameter index is known, locate the value in p->aVar[]. Then render |
-** the value as a literal in place of the host parameter name. |
