|
| -** string contains a copy of zRawSql but with host parameters expanded to

| -** their current bindings. Or, if sqlite3.nVdbeExec is greater than 1,

|
| -** 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

|
| -** 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.
