Method Detail

values

public static DriverInfo[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DriverInfo c : DriverInfo.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DriverInfo valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getDriverBaseName

public java.lang.String getDriverBaseName()

getDriversInUse

public java.util.Map<java.lang.String,java.util.Set<java.lang.String>> getDriversInUse()

For logging/testing purposes, helps to know the full driver name. Typically, there is only one, unless multiple dbconfigs are in use with multiple/untested drivers.

requiresQueryExecForTableName

public boolean requiresQueryExecForTableName()

Some drivers' query column metadata does not provide the table name info if the query is not first executed before metadata collected. As a consequence, we must execute the query before we get metadata (ouch) or use an off-the-shelf parser to infer the table name (ouch).

Perpetrators: Oracle, SqlServer

flakyParameterMetadata

public boolean flakyParameterMetadata()

(circus music) Some drivers don't provide query parameter types when the parameter's value is not set O_o For instance, depending on the version, SQLite will either return VARCHAR for all parameters or it will throw an exception when a parameter is not set. Similarly, Mysql throws the exception too unless the "generateSimpleParameterMetadata" url parameter is set in which case it provides the same VARCHAR crap sandwich as sqlite (as tested with mysql driver 8.1).

Perpetrators: SQLite, MySQL

lookup

public static DriverInfo lookup(java.sql.DatabaseMetaData metadata)
                         throws java.sql.SQLException

Throws:

java.sql.SQLException
