Detailed Description

These DBI functions were added in Qore 0.8.6; the original functions used camel case names and had NOOP variants (see Old DBI Functions)

Datasource Hash

Key	Description
`type`	the name of the driver, if present
`user`	the username given in the string
`pass`	the password for the connection
`db`	the database name for the connection
`charset`	The name of the DB-specific character encoding to use for the connection, if present in the string
`host`	the hostname for the connection, if present in the string
`port`	the port number to use for the connection, if present in the string
`options`	A hash of options given in the string, if present. Special options are `"min"` and `"max"`, which are respected by the DatasourcePool::constructor(hash) variant for setting the minimum and maximum connections in the pool, respectively; other options are passed to the DBI driver

Function Documentation

◆ dbi_get_driver_capabilities()

int Qore::SQL::dbi_get_driver_capabilities ( string driver )

Returns an integer representing the capabilities of a DBI driver binary-OR'ed together (see DBI Capability Constants) or 0 if the driver is not already loaded.

Code Flags:: CONSTANT

Parameters

driver the name of the driver; if the given driver is not already loaded then this function returns NOTHING

Returns: an integer representing the capabilities of a DBI driver binary-OR'ed together (see DBI Capability Constants) or 0 if the driver is not already loaded

Example:: int caps = dbi_get_driver_capabilities("pgsql");

Note: similar to getDBIDriverCapabilities() except uses the standard function naming scheme (ie "names_like_this()" instead of "camelCase()"), always returns an int, and does not have a NOOP variant

Since: Qore 0.8.6

◆ dbi_get_driver_capability_list()

*list< string > Qore::SQL::dbi_get_driver_capability_list ( string driver )

Returns a list of each capability supported by the given DBI driver (see DBI Capability Constants) or NOTHING if the driver cannot be found.

Code Flags:: CONSTANT

Parameters

driver the name of the driver; if the given driver is not loaded then the function returns NOTHING

Returns: a list of each capability supported by the given DBI driver (see DBI Capability Constants) or NOTHING if the driver cannot be found

Example:: *list<string> l = dbi_get_driver_capability_list("pgsql");

Note: similar to getDBIDriverCapabilityList() except uses the standard function naming scheme (ie "names_like_this()" instead of "camelCase()") and does not have a NOOP variant

Since: Qore 0.8.6

◆ dbi_get_driver_list()

*list< string > Qore::SQL::dbi_get_driver_list ( )

Returns a list of strings of DBI drivers currently loaded or NOTHING if no drivers are loaded.

Returns: a list of strings of DBI drivers currently loaded or NOTHING if no drivers are loaded

Code Flags:: CONSTANT

Example:: *list<string> l = dbi_get_driver_list();

Note: similar to getDBIDriverList() except uses the standard function naming scheme (ie "names_like_this()" instead of "camelCase()")

Since: Qore 0.8.6

◆ dbi_get_driver_options()

*hash< auto > Qore::SQL::dbi_get_driver_options ( string driver )

returns a hash of driver options

Code Flags:: CONSTANT

Parameters

driver the name of the driver; if the given driver is not already loaded then this function returns NOTHING

Returns

if the given driver is not already loaded then the function returns NOTHING; if the driver does not support any options then an empty hash is returned, otherwise a hash is returned where the keys are valid option names, and the values are hashes with the following keys:

"desc": a string description of the option
"type": a string giving the data type restriction for the option

Example:: *hash<auto> h = dbi_get_driver_options("pgsql");

Since: Qore 0.8.6

◆ parse_datasource()

hash< auto > Qore::SQL::parse_datasource ( string ds )

Returns a datasource hash of the components of a datasource string.

Code Flags:: RET_VALUE_ONLY

Parameters

ds	a string describing the datasource with the following syntax: `[`driver`:][`user`]:[/`pass`]@`db`[(`charset`)][%`host`[:`port`][{`option`=`val`[,...]}]` where all elements except `@`db are optional

Returns: a datasource hash of the components of a datasource string

Example:: hash<auto> h = parse_datasource("pgsql:user/pass@dbname(utf8)%dbhost.internal:1521{min=4,max=10}");

Exceptions

DATASOURCE-PARSE-ERROR a syntax error occurred parsing the datasource string (missing field, unexpected character, etc)

Note: similar to parseDatasource() except uses the standard function naming scheme (ie "names_like_this()" instead of "camelCase()") and does not have a NOOP variant

Since: Qore 0.8.6
