+# Query Patterns
+
+## Filtering
+
+**JavaScript:**
+
+```javascript
+// Equality
+const { data } = await supabase
+  .from("users")
+  .select("*")
+  .eq("status", "active");
+
+// Comparison
+const { data } = await supabase
+  .from("users")
+  .select("*")
+  .gte("age", 18)
+  .lt("age", 65);
+
+// Pattern matching
+const { data } = await supabase
+  .from("users")
+  .select("*")
+  .ilike("name", "%john%");
+
+// IN operator
+const { data } = await supabase
+  .from("users")
+  .select("*")
+  .in("role", ["admin", "moderator"]);
+
+// OR conditions
+const { data } = await supabase
+  .from("posts")
+  .select("*")
+  .or("status.eq.featured,priority.gte.5");
+
+// NOT
+const { data } = await supabase
+  .from("users")
+  .select("*")
+  .not("status", "eq", "banned");
+
+// NULL check
+const { data } = await supabase
+  .from("users")
+  .select("*")
+  .is("deleted_at", null);
+
+// Array contains
+const { data } = await supabase
+  .from("posts")
+  .select("*")
+  .contains("tags", ["javascript"]);
+
+// Full-text search
+const { data } = await supabase
+  .from("posts")
+  .select("*")
+  .textSearch("content", "supabase & database");
+```
+
+**Python:**
+
+```python
+# Equality
+response = supabase.table("users").select("*").eq("status", "active").execute()
+
+# Comparison
+response = supabase.table("users").select("*").gte("age", 18).lt("age", 65).execute()
+
+# Pattern matching (case-insensitive)
+response = supabase.table("users").select("*").ilike("name", "%john%").execute()
+
+# IN operator
+response = supabase.table("users").select("*").in_("role", ["admin", "moderator"]).execute()
+
+# OR conditions
+response = supabase.table("posts").select("*").or_("status.eq.featured,priority.gte.5").execute()
+
+# NOT
+response = supabase.table("users").select("*").neq("status", "banned").execute()
+
+# NULL check
+response = supabase.table("users").select("*").is_("deleted_at", "null").execute()
+```
+
+## Pagination
+
+**Offset-based (simple, less efficient for large datasets):**
+
+```javascript
+// JavaScript
+const { data } = await supabase
+  .from("posts")
+  .select("*")
+  .order("created_at", { ascending: false })
+  .range(0, 9); // rows 0-9 (first 10)
+
+// Next page
+const { data } = await supabase
+  .from("posts")
+  .select("*")
+  .order("created_at", { ascending: false })
+  .range(10, 19);
+```
+
+```python
+# Python
+response = supabase.table("posts").select("*").order("created_at", desc=True).range(0, 9).execute()
+```
+
+**Cursor-based (efficient for large datasets):**
+
+```javascript
+// JavaScript - use last item's id/timestamp as cursor
+const { data } = await supabase
+  .from("posts")
+  .select("*")
+  .order("created_at", { ascending: false })
+  .lt("created_at", lastTimestamp)
+  .limit(10);
+```
+
+```python
+# Python
+response = (
+    supabase.table("posts")
+    .select("*")
+    .order("created_at", desc=True)
+    .lt("created_at", last_timestamp)
+    .limit(10)
+    .execute()
+)
+```
+
+## Counting Rows
+
+```javascript
+// JavaScript - exact count
+const { count } = await supabase
+  .from("users")
+  .select("*", { count: "exact", head: true })
+  .eq("status", "active");
+
+console.log(`Active users: ${count}`);
+```
+
+```python
+# Python
+response = supabase.table("users").select("*", count="exact", head=True).eq("status", "active").execute()
+
+print(f"Active users: {response.count}")
+```
+
+## Index Recommendations
+
+Add indexes for frequently filtered/sorted columns:
+
+```sql
+-- Single column index
+create index idx_posts_status on posts (status);
+
+-- Composite index for common filter combinations
+create index idx_posts_user_status on posts (user_id, status);
+
+-- Partial index for specific conditions
+create index idx_active_posts on posts (created_at) where status = 'active';
+
+-- Use index_advisor for recommendations
+select * from index_advisor('SELECT * FROM posts WHERE status = ''active'' ORDER BY created_at');
+```
+
+## Query Performance Analysis
+
+```sql
+-- Analyze query execution plan
+explain analyze select * from posts where status = 'active' order by created_at limit 10;
+```
