lrd_ora8_handle_alloc

lrd_ora8_handle_alloc 函数分配并初始化LRDBI句柄。句柄类型只由限定符指定。限定符是LRD_HTYPE_ORACLE_ 字符串的唯一后缀。例如，在LRD_HTYPE_ORACLE_SESSION 中，限定符是“SESSION”。

LRDRET lrd_ora8_handle_alloc ( void const * mpvParentHandle, long const mliDBHandleType, void * * const mppvLRDDBIHandle, int const miDBErrorSeverity );

lrd_server_attach

lrd_ora8_attr_set_from_handle

lrd_ora8_attr_set_from_handle 函数设置LRDDBI句柄的属性。在使用lrd_handle_alloc调用此函数之前，必须显式地分配句柄。只有Oracle 8.0 和更高版本才支持此函数。

LRDRET lrd_ora8_attr_set_from_handle ( void *mpvLRDDBIHandleTarget, long mliAttrType, void *mpvValue, long mliValueLen, int miDBErrorSeverity )

lrd_ora8_attr_set

lrd_ora8_attr_set 函数设置LRDDBI 句柄的属性。在使用lrd_handle_alloc 调用此函数前必须显式分配句柄。只有Oracle 8.0 和更高版本才支持此函数。

LRDRET lrd_ora8_attr_set ( void *mpvLRDDBIHandleTarget, long mliAttrType, void *mpvValue, long mliValueLen, int miDBErrorSeverity );

lrd_session_begin

lrd_session_begin 函数启动服务器的用户会话。只有Oracle 8.0 和更高版本才支持此函数。

LRDRET lrd_session_begin ( void *mpvLRDDBIHandleSvcCtx, void *mpvLRDDBIHandleSession, unsigned long muliCredentials, long mliMode, int miDBErrorSeverity );

lrd_ora8_stmt

lrd_ora8_stmt 函数准备用于执行的SQL或PL/SQL语句。语句的文本是null终止字符串，在该字符串中没有任何null 字符。（对于包含null 字符的字符串，请使用lrd_ora8_stmt_literal 或lrd_ora8_stmt_ext。）

LRDRET lrd_ora8_stmt (void *mpvLRDDBIHandleStmt, char *mpcStmtText, long mliLanguage, long mliMode, int miDBErrorSeverity );

lrd_ora8_exec

lrd_ora8_exec 函数执行lrd_stmt 设置的SQL 语句。此函数重置由lrd_ora8_stmt 设置的SQL 语句内容；在每个lrd_ora8_exec 函数调用之后，您必须提供新的语句（并可选择绑定参数）。

LRDRET lrd_ora8_exec ( void *mpvLRDDBIHandleSvcCtx, char *mpvLRDDBIHandleStmt, unsigned long muliTotalRows, unsigned long muliSkipRows, unsigned long *mpuliRowsProcessed, LRD_ORA8_PRINT_ROW_TYPEDEF mpfjPrintRow, void *Reserved1,void *Reserved2, long mliMode, int miDBErrorSeverity );

lrd_ora8_bind_col

lrd_ora8_bind_col 函数将主机变量绑定到输出列。VuGen 为结果集中的所有列生成lrd_ora8_bind_col 语句。

LRDRET lrd_ora8_bind_col (void *mpvLRDDBIHandleStmt, void 阿祖总结－Zu.Stone@QQ.com 54**mppvLRDDBIHandleDefine, int muiColNum, LRD_VAR_DESC *mptVarDesc, long mliMode, int miDBErrorSeverity );

lrd_ora8_fetch

lrd_ora8_fetch 函数从结果集中提取后续若干行。在录制的脚本中，结果集中的行数是参数mliRequestedRows的绝对值。例如，如果lrd_ora8_fetch 的第二个参数是-14，则检索了十四行数据。

LRDRET lrd_ora8_fetch (void *mpvLRDDBIHandleStmt, long mliRequestedRows, long mliRowsBatchSize, unsigned long *mpuliFetchedRows, LRD_PRINT_ROW_TYPEDEF mpfjPrintRow, long mliOrientation, long mliMode, int miDBErrorSeverity );

lrd_handle_free

lrd_handle_free 函数显式地释放LRDDDBI 句柄。注意，句柄必须已被显式地（使用lrd_handle_alloc）或隐式地（使用lrd_logon）分配。只有Oracle 8.0 和更高版本才支持此函数。

LRDRET lrd_handle_free ( void **mppvLRDDBIHandle, int miDBErrorSeverity);

lrd_assign

lrd_assign 函数将null 终止字符串（文字或存储区域）通过其描述符分配给变量。必要时，字符串将被转换为变量的数据类型和长度。若要在字符串中包含null 字符('\0')，或者如果字符串不是null 终止的，请使用lrd_assign_ext 或lrd_assign_literal。只能通过指定NULL 或0（不带引号），才能为lrd_assign 分配NULL 值。

LRDRET lrd_assign ( LRD_VAR_DESC *mptVarDesc, char *mpcValStr, char *mpszValStrFmt, unsigned long muliIndex, long mliOffset );

lrd_ora8_bind_placeholder

lrd_ora8_bind_placeholder 函数将主机变量或数组绑定到占位符。此函数要与lrd_assign 配合使用。

LRDRET lrd_ora8_bind_placeholder (void *mpvLRDDBIHandleStmt, void **mppvLRDDBIHandleBind, char *mpszPlaceholder, LRD_VAR_DESC *mptVarDesc, unsigned long muliOption, long mliMode, int miDBErrorSeverity );

lrd_ora8_print

lrd_ora8_commit

lrd_ora8_commit 函数从Oracle 8.x 客户端的上一保存点提交当前数据库事务。

LRDRET lrd_ora8_commit ( void *ServiceContextHandle, long Mode, int ErrorSeverity );

lrd_session_end

lrd_session_end 函数结束服务器的用户会话。只有Oracle 8.0 和更高版本才支持此函数。

LRDRET lrd_session_end ( void const *mpvLRDDBIHandleSvcCtx, void const *mpvLRDDBIHandleSession, long const mliMode, int const miDBErrorSeverity );

lrd_server_detach

lrd_server_detach 函数删除用于数据库操作的数据源的访问路径。只有Oracle 8.0 和更高版本才支持此函数。

LRDRET lrd_server_detach ( void const * mpvLRDDBIHandleServer, long const mliMode, int const miDBErrorSeverity );
