Issue:
Add Select operation
Currently, we only support cache-based listing using `client.List()`. Filtering can be performed by using `WhereCache()`. However, this makes it mandatory for clients to use Monitor() so the client registers all the DB updates and populates the cache. This has a significant performance (both in terms of memory and cpu) and might not be desired by the user.

We should support RFC7047 Select operation to allow users to inspect the database without having an in-memory copy of it.

My proposal for the API is to leave List() and Get() for cache-based operations and add a new API method called `Select` that performs the homonym operation.


Discussion:
@amorenoz: With regards to the API, I'm tempted to hide the `ovsdb.Operation`, make the transaction and return a list of elements. @dave-tucker , do you think `Select` operations are likely to be batched into larger transactions?@dave-tucker: @amorenoz hmmm. I don't think it's likely to be batched, but for to be consistent with other operations it would be better to have it return `[]ovsdb.Operation`. That way the client has total control over how things are run.@rutuja-clusters: Just wanted to know, is there an estimate by when this feature may be added. 

@dave-tucker @amorenoz It would help if you could let me know,  is there a group where doubts are discussed? I tried to join the [slack channel](https://ovn-org.slack.com/signup#/domain-signup) mentioned in the readme but it asks to contact the workspace administrator (if not from redhat/nvidia). 
Thanks@amorenoz: Hi @rutuja-clusters , sorry I have missed your comment. I don't understand why you are not being able to join the slack channel. It's part of the ovn-org.slack.com. I'll ask around to see who can help here.

As for the ETA for this, we haven't had much push on this feature because of the possibility of using `WhereCache`. I don't know what the plans are on this. Any idea @flavio-fernandes @jcaamano ?@jcaamano: There are no plans that I am aware of about this topic. 

It should be straight forward enough to have a Select operation. I guess we would need to add as well an additional utility method able to parse the models from the results?

Also the added support of conditional monitoring might alleviate some of the initial concerns @amorenoz  had in the issue opener. @yuyang0: @jcaamano any updaes of this issue? Select operation is very useful in some sceneries.@jcaamano: @yuyang0 no updates. Would you be willing to contribute a PR towards this? Otherwise it is just a matter of finding the time to do it.

+### Querying with Select
+
+The `Select` operation is used to build an OVSDB `select` query. Unlike the `List` operation, which returns results directly from the cache, `Select` only generates `ovsdb.Operation`(s). You must pass these operations to `Transact` to execute them against the database, and then use a helper function like `GetSelectResults` to parse the reply.
+
+The `Select` operation can be used in two ways:
+- **Direct Select**: Call `Select()` directly on the API for unconditional selection (selects all rows from a table)
+- **Conditional Select**: Call `Select()` on a `ConditionalAPI` created with `WhereXxx()` methods for filtered selection
+
+The core workflows are:
+- **Direct**: `ovs.Select(model, fields...) -> Transact(...) -> GetSelectResults(...)`
+- **Conditional**: `ovs.WhereXxx(...).Select(model, fields...) -> Transact(...) -> GetSelectResults(...)`
+
+#### Selecting Rows
+
+**Select All Rows from a Table:**
+
+To select all rows from a table, call `Select()` directly on the API. The model instance is used only to determine the target table and doesn't filter results.
+
+    // var ovs client.Client
+    // var ctx context.Context
+    var allSwitches []*MyLogicalSwitch // Target must be a slice of pointers to models
+    // 1. Generate Op: Direct Select selects all rows
+    selectOps, err := ovs.Select(&MyLogicalSwitch{})
+    // ...
+    // 2. Execute transaction
+    reply, err := ovs.Transact(ctx, selectOps...)
+    // ...
+    // 3. Parse result
+    err = ovs.GetSelectResults(selectOps, reply, &allSwitches)
+    // ...
+
+**Select by Index:**
+
+You can use `Where()` with a model instance that has indexed fields populated. This will create a condition to find matching rows based on the first available index.
+
+    // Assuming "Name" is an indexed field
+    ls := &MyLogicalSwitch{Name: "switch1"}
+    var results []*MyLogicalSwitch
+    // 1. Generate Op
+    selectOps, err := ovs.Where(ls).Select(ls)
+    // ...
+    // 2. Transact and parse
+    reply, err := ovs.Transact(ctx, selectOps...)
+    err = ovs.GetSelectResults(selectOps, reply, &results)
+    // ...
+
+**Select with Conditions (AND):**
+
+Use `WhereAll()` to set the table context and one or more filter conditions. All conditions are combined with an `AND` operator.
+
+    var specificSwitches []*MyLogicalSwitch
+    lsModel := &MyLogicalSwitch{}
+    cond1 := model.Condition{Field: &lsModel.Name, Function: ovsdb.ConditionEqual, Value: "sw1"}
+    cond2 := model.Condition{Field: &lsModel.Ports, Function: ovsdb.ConditionIncludes, Value: "some_port_uuid"}
+
+    // 1. Generate Op: Use WhereAll for one or more AND conditions
+    selectOps, err := ovs.WhereAll(lsModel, cond1, cond2).Select(lsModel)
+    // ...
+    // 2. Transact and parse
+    reply, err := ovs.Transact(ctx, selectOps...)
+    err = ovs.GetSelectResults(selectOps, reply, &specificSwitches)
+    // ...
+
+**Select with Conditions (OR):**
+
+Use `WhereAny()` to set the table context and one or more filter conditions. `WhereAny` will generate one `select` operation per condition. All generated operations belong to the same select query, allowing `GetSelectResults` to aggregate the results into a single slice.
+
+    var specificSwitches []*MyLogicalSwitch
+    lsModel := &MyLogicalSwitch{}
+    cond1 := model.Condition{Field: &lsModel.Name, Function: ovsdb.ConditionEqual, Value: "sw1"}
+    cond2 := model.Condition{Field: &lsModel.Ports, Function: ovsdb.ConditionIncludes, Value: "some_port_uuid"}
+
+    // 1. Generate Ops: Use WhereAny for one or more OR conditions
+    // This generates multiple operations, one for each condition
+    selectOps, err := ovs.WhereAny(lsModel, cond1, cond2).Select(lsModel)
+    // ...
+    // 2. Transact and parse
+    reply, err := ovs.Transact(ctx, selectOps...)
+    // GetSelectResults will parse all results and populate them into the target slice.
+    err = ovs.GetSelectResults(selectOps, reply, &specificSwitches)
+    // ...
+
+**Select with Cache-based Filtering:**
+
+Use `WhereCache()` to filter rows based on a predicate function that operates on cached data. This generates one `select` operation per matching cached row, using UUID-based conditions. All generated operations belong to the same select query.
+
+    var matchingSwitches []*MyLogicalSwitch
+
+    // 1. Generate Ops: Use WhereCache with a predicate function
+    // This generates multiple operations, one for each matching row in cache
+    selectOps, err := ovs.WhereCache(func(ls *MyLogicalSwitch) bool {
+        return strings.HasPrefix(ls.Name, "ext_")
+    }).Select(&MyLogicalSwitch{})
+    // ...
+    // 2. Transact and parse
+    reply, err := ovs.Transact(ctx, selectOps...)
+    // GetSelectResults will parse all results and populate them into the target slice.
+    err = ovs.GetSelectResults(selectOps, reply, &matchingSwitches)
+    // ...
+
+#### Selecting Specific Columns
+
+By default, `Select` queries all columns of a table. You can pass field pointers to the `Select` method to retrieve only specific columns. The `_uuid` column is always included in the result.
+
+**For Direct Select (all rows with specific columns):**
+
+    // Selects only the "name" and "ports" columns for all rows using field pointers
+    ls := &MyLogicalSwitch{}
+    selectOps, err := ovs.Select(ls, &ls.Name, &ls.Ports)
+
+**For Conditional Select (filtered rows with specific columns):**
+
+    // Selects only the "name" and "ports" columns for rows matching the condition
+    ls := &MyLogicalSwitch{Name: "sw1"}
+    selectOps, err := ovs.Where(ls).Select(ls, &ls.Name, &ls.Ports)
+
+#### Processing Select Results with GetSelectResults and GetSelectResultsByIndex
+
+Multiple `Select()` operations can be bundled within a transaction.
+**GetSelectResults** retrieves the results for the first select operation.
+**GetSelectResultsByIndex** allows you to choose which select operation to retrieve the results for:
+
+    // Example: Multiple separate Select() calls for the same model
+    var ptrResults1, ptrResults2 []*MyLogicalSwitch  // Target must be a pointer slice
+
+    // First Select() call - creates select query #0
+    ls1 := &MyLogicalSwitch{Name: "sw1"}
+    selectOps1, _ := ovs.Where(ls1).Select(ls1)
+
+    // Second Select() call - creates select query #1
+    ls2 := &MyLogicalSwitch{Name: "sw2"}
+    selectOps2, _ := ovs.Where(ls2).Select(ls2)
+
+    // Combine operations for a single transaction
+    allOps := append(selectOps1, selectOps2...)
+    reply, _ := ovs.Transact(ctx, allOps...)
+
+    // Get results from first Select() call (index 0)
+    err = ovs.GetSelectResults(allOps, reply, &ptrResults1)
+    err = ovs.GetSelectResultsByIndex(allOps, reply, &ptrResults1, 0) // Explicit index 0
+
+    // Get results from second Select() call (index 1)
+    err = ovs.GetSelectResultsByIndex(allOps, reply, &ptrResults2, 1)
+
 ## Monitor for updates
 
 You can also register a notification handler to get notified every time an element is added, deleted or updated from the database.
