REL-07_03_ENHANCED code branchof psqlODBC - please see <a href="http://archives.postgresql.org/pgsql-odbc/2006-02/msg00131.php">http://archives.postgresql.org/pgsql-odbc/2006-02/msg00131.php</a>for further details.</p><p>The following changes are based on the 07.03 codebase</p><pre>[7.3.0261]1.Handle the converion from text-like field to SQL_C_BINARY more properly.2.Make buffer extension in SQLPutData more effective.3.Reply SQL_CONVERT_xxxx correctly for SQLGetInfo request.4.Reply DBMS_NAME, DBMS_VERSION correctly for SQLGetInfo request.5.Not call show max_identifier_length in PG 7.4.6.Change adjustLikePattern() to take literal quote(') into account.7.Fix a bug in memory debug routine.8.Change the multibyte encoding list to match that of the current offical driver.9.Change SC_clear_error() to call CC_clear_error() also.10.Change the length values returned when they are unknown for SQLDescribeCol or SQLColAttribute requests.[7.3.0261]1.Fix the handling of *too small buffer* in the Unicode version.2.Fix the behavior of DiscardStatementSvp which resets the status too early.3.Fix the bug in PGAPI_ParamData which fails to count the number of parameters.4.Allow blanks in password.5.Add an option to force abbreviation of connection string.6.Fix the handling of "PROTOCOL=x.x-x" in the connction string.7.Fix the loadlib module of *nix.[7.3.0260]1. Change delay load import library mechanism(libpq,openssl)2. Compile Optimization correspondence.3. SQLForeignKeys ResultSet accuracy correspondence.[7.3.0258]1. bug fix: SQLBulkOperations rollback option. There was a case where a rollback was not published in SQLBulkOperations as option specification at the time of error generating.[7.3.0257]1. Fault correction of the division SQLGetData to SQL_C_WCHAR.[7.3.0256]1. SQLSetPos does not position to current-row to renewal of unblock cursor. (Data is unacquirable by SQLGetData etc.)[7.3.0255]1. bug fix: leak of a return value clearance2. Correspondence Windows English Dialog.3. Changes into the libpq link method.[7.3.0254]1. Setting menu of SSLMODE is added.2. Correspondence to domain type lo (an approvement is still required).3. bug fix: LIBPQ version cancellation request transmitting correspondence.4. Correction of the exclusive control between threads of SQLCancel[7.3.0253]1. Compilation of escape usage. (preliminaries corresponding to a literal-escape abolition schedule)2. Correspondence of libpq and openssl.3. SQLProcedureColumns()RESULT_COLS row is outputted.4. bug fix: server-side prepare the number check of parameters.5. bug fix: parameter bind without a parameter marker is disregarded.6. bug fix: Retrying without carrying out a select operation to EWOULDBLOCK of socket/SSL-read.7. Abolition of abolition in manual_result mode, TupleList, and TupleNode employment[7.3.0252]1. Bug fix: Multi-byte employment by a table name etc.2. The text (varchar/char) type key assignation was enabled by MS-Access.[7.3.0251]1. Suppression of SQLColumnPrivilege support It rejects using information_schema.column_privileges.2. Binary mode is used for a bytea type parameter value setup. (Performs by the sequence of SQLPrepare->SQLExecute by server_side_prepare employment)3. Coexistence of LO type and bytea type. When the parameter of LongVarBinary exists not by SQLPrepare->SQLExecute but by SQLExecDirect at the time of direct dispatching, the Parse/Describe function of a protocol 3 is used, the model in saver of LongVarBinary is acquired beforehand, and a bytea type and LO type are recognized.[Feature of Driver7.3.025x]1. Correspondence protocol 3 Options, such as client encoding, are set up by the start-up packet. This makes the most of the mechanism of Parse/Bind/Execute.⌨️ 快捷键说明
