Begin an McDBQuery condition assignment precedence level, following ordinary parenthetical precedence rules.

None  

object.OpenBracket

The OpenBracket Method syntax has these parts:

McDBQuery objects encapsulate queries that honor explicit precendence rules for operators. For example, the query: Name=<NameVal1> OR Name=<NameVal2> AND Type=<TypeVal> can be interpreted in two manners:

(Name=<NameVal1> OR Name=<NameVal2>) AND Type=<TypeVal>

or

Name=<NameVal1> OR (Name=<NameVal2> AND Type=<TypeVal>)

This method allows resolution of this ambiguity. See the Example.

Error	Value	Description
E_PENDING	&H8000000A	The database context has not been established. Call AttachDatabase().

It is necessary to call CloseBracket once for each call to OpenBracket, or else the McDBQuery will fail, when executed. This type of Syntax checking for the McDBQuery being formed is not done until it is executed.
