## Function Documentation

sqlrcon sqlrcon_alloc | ( | const char * | server,
|  | uint16_t | port,
|  | const char * | socket,
|  | const char * | user,
|  | const char * | password,
|  | int32_t | retrytime,
|  | int32_t | tries
| ) |  |

Initiates a connection to "server" on "port" or to the unix "socket" on the local machine and authenticates with "user" and "password". Failed connections will be retried for "tries" times on interval "retrytime". If "tries" is 0 then retries will continue forever. If "retrytime" is 0 then retries will be attempted on a default interval. If the "socket" parameter is nether NULL nor "" then an attempt will be made to connect through it before attempting to connect to "server" on "port". If it is NULL or "" then no attempt will be made to connect through the socket.

int sqlrcon_autoCommitOff | ( | sqlrcon | sqlrconref | ) |

Instructs the database to wait for the client to tell it when to commit.

int sqlrcon_autoCommitOn | ( | sqlrcon | sqlrconref | ) |

Instructs the database to perform a commit after every successful query.

const char* sqlrcon_bindFormat | ( | sqlrcon | sqlrconref | ) |

Returns a string representing the format of the bind variables used in the db.

void sqlrcon_debugOff | ( | sqlrcon | sqlrconref | ) |

Turns debugging off.

void sqlrcon_debugOn | ( | sqlrcon | sqlrconref | ) |

void sqlrcon_debugPrintFunction | ( | sqlrcon | sqlrconref,
|  | int(*)(const char *,...) | printfunction

Ends the session.

const char* sqlrcon_errorMessage | ( | sqlrcon | sqlrconref | ) |

If an operation failed and generated an error, the error message is available here. If there is no error then this method returns NULL

void sqlrcon_free | ( | sqlrcon | sqlrconref | ) |

Disconnects and ends the session if it hasn't been terminated already.

uint16_t sqlrcon_getConnectionPort | ( | sqlrcon | sqlrconref | ) |

Returns the inet port that the connection is communicating over. This parameter may be passed to another connection for use in the sqlrcon_resumeSession() command. Note: The result this function returns is only valid after a call to suspendSession().

const char* sqlrcon_getConnectionSocket | ( | sqlrcon | sqlrconref | ) |

Returns the unix socket that the connection is communicating over. This parameter may be passed to another connection for use in the sqlrcon_resumeSession() command. Note: The result this function returns is only valid after a call to suspendSession().

int sqlrcon_ping | ( | sqlrcon | sqlrconref | ) |

Returns 1 if the database is up and 0 if it's down.

int sqlrcon_resumeSession | ( | sqlrcon | sqlrconref,
|  | uint16_t | port,
|  | const char * | socket
| ) |  |

Resumes a session previously left open using sqlrcon_suspendSession(). Returns 1 on success and 0 on failure.

void sqlrcon_setTimeout | ( | sqlrcon | sqlrconref,
|  | int32_t | timeoutsec,

| ) |  |

Sets the server connect timeout in seconds and milliseconds. Setting either parameter to -1 disables the timeout.

int sqlrcon_suspendSession | ( | sqlrcon | sqlrconref | ) |

Disconnects this connection from the current session but leaves the session open so that another connection can connect to it using sqlrcon_resumeSession().

uint64_t sqlrcur_affectedRows | ( | sqlrcur | sqlrcurref | ) |

Returns the number of rows that were updated, inserted or deleted by the query. Not all databases support this call. Don't use it for applications which are designed to be portable across databases. -1 is returned by databases which don't support this option.

sqlrcur sqlrcur_alloc | ( | sqlrcon | sqlrconref | ) |

Creates a cursor to run queries and fetch result sets using connection "sqlrconref"

A default time-to-live of 10 minutes is also set.

Note that once sqlrcur_cacheToFile() is called, the result sets of all future queries will be cached to that file until another call to sqlrcur_cacheToFile() changes which file to cache to or a call to sqlrcur_cacheOff() turns off caching.

Defines a string output bind variable. "length" bytes will be reserved to store the value.

void sqlrcur_dontGetColumnInfo | ( | sqlrcur | sqlrcurref | ) |

Tells the server not to send any column info (names, types, sizes). If you don't need that info, you should call this function to improve performance.

int sqlrcur_endOfResultSet | ( | sqlrcur | sqlrcurref | ) |
